MODELMATCH 

Patent pending ModelMatch technology prevents the operation of your model, 

if you select the wrong model memory. During binding the receiver learns the 

model’s memory (1 through 30) the transmitter is currently programmed to. 

Later, if you select the incorrect model memory in the transmitter and turn the 

receiver on, the model won’t operate. This prevents a possible crash. Change the 

programming to the correct model memory, and you can fly. 

ADvANCED DIGITAL TRIMS 

The 11X features Advanced digital trims. On the Normal display screen, if you 

move a trim lever, the screen automatically displays the graphic position for the 

trim being adjusted. The 11X Aileron, Elevator and Rudder trim levers and the 

right and left rear levers feature an audible center trim beep. This helps when 

determining the trim lever’s center position during flight. In addition, the frequency 

of each trim step changes from full right/up to full left/down on the three front 

digital trims. This allows you to be aware of the general trim position audibly 

without looking at the transmitter. 

By using the Trim System Function located in the System List, you can adjust the 

amount of travel per each trim step as needed for your specific application. When 

you turn the 11X off, the transmitter stores the trim values and recalls them when 

turned back on.

AR6000, AR6100, AR6100e, AR6110, AR6110E, AR6300, AR6400 and 

AR7600 when the remote receiver is not connected), you should only fly these 

receivers in park flyer-type aircraft (small electric airplanes or mini and micro 

helicopters). Flying receivers designed for park flyers in larger aircraft could 

cause a loss of control resulting in damage to property and/or injury. 

CHARGING 

Do’s and Don’ts 

• Charge transmitter and receiver battery before flying. 

• Check receiver battery charge between each flight using a tester with built-in 

load. 

• Only use charger on JR equipment. Charge plug polarity may be different. 

Equipment damage can result. 

• Do not use other manufacturer’s after-market accessories that plug into 

transmitter charging jack. If you doubt polarity compatibility, seek expert 

advice to avoid possible damage. 

• The center pin on all JR transmitters is negative. Therefore, all JR chargers 

have a negative center pin, not positive. 

• Beware of improper connections based on color-coded wire leads—they 

may not apply. 

• ALWAYS connect the center pin of y our JR transmitter to the negative pole 

for correct polarity. 

Instructions 

1. Plug the charger into the 11X battery port on the right side of the radio. 

2. Plug the charger power supply into the wall outlet. 

CAUTION: Not following proper sequence of numbers 1 and 2 can cause a 

static short, which could damage the battery circuitry. 

3. For initial charge and any charging of fully discharged battery, charge time 

is 10–12 hours. Charge time decreases if battery is not fully discharged. 

4. Monitor the temperature of battery during charging. 

5. After charging, check the voltage of the battery pack by turning system on. 

Voltage should be just over 11 volts (11.4 approximately but will vary). 

6. During first use, battery voltage may drop below 9.6 volts. Charge the 

battery again to just over 11 volts. Do not overcharge. 

Notes 

• The 11X battery contains a heat detector. If it senses excessive heat, it shuts 

off the charger and shows an error on the charger LED. 

• The battery voltage does not affect the output of the system as the output is 

regulated internally. 

• The 11X charger is not a peak detect charger. If using a fast charger for 

the transmitter battery, do not exceed 1.5 amps (1500mA) charge rate or 

damage to transmitter or battery can occur. 

• The 11X charger output is DC 11.6V, with 110mA as the average charge rate. 

• If using a peak detection charger, make sure battery is fully charged. NiMH 

batteries tend to repeatedly false peak with peak detection fast chargers. Use 

a charger that displays the total charge current. Note the number of mAh put 

into a discharged pack to verify it charges to capacity. 

Safety Precautions and Warnings 

Failure to exercise caution while using this product and comply with the 

following warnings could result in product malfunction, electrical issues, 

excessive heat, FIRE, and ultimately injury and property damage. 

• If the transmitter voltage drops below 9.0 volts or the battery alarm goes off 

during flight, land immediately and recharge. 

• Read all safety precautions and literature prior to use of this product. 

• Never leave battery and charger unattended during use. 

• Never allow minors to charge battery packs without adult supervision. 

• Never attempt to charge dead or damaged batteries. 

• Never charge a battery if the cable has been pinched or shorted. 

• Never allow batteries or charger to come into contact with moisture at any 

time. 

• Never charge batteries in extremely hot or cold places (recommended 

between 50–80 drees Fahrenheit) or place in direct sunlight. 

• Always use only compatible NiMH rechargeable batteries. This charger 

cannot charge batteries such as “heavy duty,” “alkaline battery,” or 

“mercury battery.” 

• Always properly connect charger and battery. 

• Always disconnect the battery and hcarger after charging, and let them cool 

between charges. 

• Always inspect the battery before charging. 

• Always terminate all processes and contact Horizon Hobby if the product 

malfunctions. 

• Always monitor battery temperature while charging. 

• End charging process if the charger or battery comes hot to the touch or 

starts to change form during the charge process.

THe JR R921 ReCeIVeR 

The JR R921 incorporates two internal receivers and one remote receiver with 

an optional second remote receiver. You must plug 1 remote receiver into one of 

the remote receiver ports for the system to operate and a second remote receiver 

(optional) into the remaining remote antenna port. 

Installing the receivers in different locations throughout the aircraft exposes 

each receiver to its own RF environment. This greatly improves the ability of 

the receivers to see the signal in all conditions. This gives a solid RF link, even 

in aircraft that have substantial conductive materials (e.g., turbine engines with 

metal tail pipes, carbon fiber, tuned pipes, etc.) that can weaken the signal. 

Installing the R921 

Install the main receiver using the same method of a conventional receiver in 

your aircraft. Typically, wrap the main receiver in protective foam and fasten it in 

place using rubber bands or hook and loop straps. Alternately in electric models 

or in jets (low vibration),you can use thick double-sided foam tape to fasten the 

main receiver in place. 

Using double-sided foam tape (servo tape), mount the remote receiver(s) 

keeping it at least 2 inches away from the primary receiver. Ideally, you should 

position the antennas perpendicular to each other. 6-, 9-, 12-, 24-, and 36-inch 

leads are available. A standard installation includes the main receiver mounted 

conventionally in the fuselage and the remote antennas in the nose (jets) in 

the top turtle deck and even in the tail. The optimum location, especially for 

sophisticated aircraft, is as far away from any conductive materials as practical. 

In helicopters, the servo tray generally has enough room to achieve the 

necessary separation. When needed you can make a mount using clear plastic to 

position the remote receiver. 

Other important installation tips: 

1. Mount the servos using rubber grommets and brass eyelets to isolate them 

from vibration. Do not over-tighten the mounting screws; this will negate 

the vibration absorption effect of the rubber grommets. When mounting, 

push the brass eyelets from the bottom up in the rubber grommets. By 

tightening the servo screw securely, you provide the proper security and 

vibration isolation for your servo. 

2. The servo arms must be able to move freely over their entire range of travel. 

Make sure the control linkages do not bind or impede the movement of any 

of the servos. 

3. Mount all switches away from the engine exhaust and away from any high 

vibration areas. Make sure the switch operates freely and over its full travel.

INDING 

Binding is necessary to program the receiver to the transmitter so the receiver 

only recognizes that specific transmitter, ignoring signals from any other sources. 

If the receiver is not bound to the transmitter, the system will not operate. During 

binding, the servo’s failsafe positions are stored. 

The following sequence describes the binding procedure for the JR R921. All JR 

and Spektrum DSM aircraft receivers are bound in the same way. 

HOW TO bIND 

Note: To bind an aircraft with an electronic speed controller that powers the 

receiver through the throttle channel (BEC), insert the bind plug into the bind port 

and proceed to Step #2. 

1. With the system hooked up as shown, insert the bind plug in the charge plug 

receptacle. The switch must be a 3-wire type switch (JRPA001 or JRPA004) 

to enter bind mode through the switch. Plug the switch into the bind port 

R921 

of the receiver. If a 3-wire switch is not available, install the male bind plug 

directly into the receiver bind receptacle and power the receiver through any 

other open port to enter bind mode. 

2. Power on the receiver. The LEDs on all receivers should be flashing, 

indicating the receiver is ready to bind. 

3. Establish the desired failsafe stick positions: normally low throttle and flight 

controls neutral. 

4. Press and hold the bind button on the back of the transmitter while turning 

on the power switch. The bind lights on the front and rear of the transmitter 

should flash and within a few seconds the system should connect. The LEDs 

on the receivers should go solid, indicating the system has connected. 

5. Remove the bind plug from the receiver or switch harness and store in a 

convenient place. 

6. After programming your model, rebind the system so the true low throttle 

and neutral control surface positions are programmed. 

7. When the transmitter is turned on and operating with the system, the amber 

light on the rear of the transmitter will be on solid. The blue light on the 

top front of the transmitter will also be on solid indicating the system is 

outputting signal and operating. 

fAILSAfE fUNCTIONS 

The JR R921 receiver features two types of failsafe programming: SmartSafe and 

Preset Failsafe. 

SmartSafe 

SmartSafe is automatically selected during the standard binding procedure and is 

ideal for electric aircraft as well as most gas- and glow-powered aircraft. 

How SmartSafe Works 

• When the Receiver is Powered On without a Transmitter Signal 

If you turn on the R291 before you turn on the transmitter, SmartSafe 

prevents the throttle from functioning and drives all other channels to their 

preset positions. 

• When there is a Loss of Signal in flight 

If the receiver loses the transmitter’s signal in flight, or any other time after 

a successful connection has been made, SmartSafe sets the throttle to the 

position it was in during the binding process. All other channels hold the 

positions they were in at signal loss. 

How to Program the Receiver for SmartSafe 

Simply move the throttle to a desired in-flight failsafe position (typically this is 

all the way back) and bind the receiver to the transmitter. Leave the bind plug in 

the receiver during the entire binding process. Remove the bind plug only after a 

connection has been made and the controls are functioning normally. 

Preset failsafe 

Preset Failsafe allows you to set the specific control positions for all channels 

to go to should you encounter signal loss in flight or at any other time after a 

successful connection has been made. Preset Failsafe is typically used to prevent 

“fly aways” in high-performance models by deploying spoilers in sailplanes or 

putting gas- and glow-powered models into a slight turn at reduced throttle. 

How to Program Preset failsafe Settings 

Insert the bind plug and power on the receiver. When the receiver’s LED lights 

begin to blink indicating it is in bind mode, remove the bind plug before binding 

the transmitter to the receiver. The LED lights on the receiver continue to blink. 

Move your transmitter’s control sticks and switches to the desired Preset Failsafe 

positions then turn it on in bind mode. The system should connect in less than 

15 seconds. 

RANGE TESTING 

The Standard Range Testing procedure is recommended for most sport aircraft. 

Range Testing 

1. With the model resting on the ground, stand 30 paces (approx. 90 feet) away 

from the model. 

2 Face the model with the transmitter in your normal flying position and 

depress and hold the bind button on the back of the transmitter. This causes 

reduced power output from the transmitter. 

3 You should have total control of the model with the button depressed at 30 

paces (90 feet). 

4 If control issues exist, call Product Support at 1-877-504-0233 for further 

assistance. 

30 paces (90 feet/27 meters) 

RECEIvER POWER SYSTEM 

ReQUIReMeNTS 

The onboard power system must provide adequate power without interruption 

to the receiver even when the servos are at maximum flight loads. Inadequate 

power systems that do not provide the necessary minimum voltage to the receiver 

during flight loads are the number one cause of in-flight failures. Some power 

system components that affect the ability to properly deliver adequate power 

include: the selected receiver battery pack (number of cells, capacity, cell type, 

state of charge), switch harness, battery leads, and if used, the regulator and 

power bus. 

Recommended Power System Guidelines 

1. When setting up large or complex aircraft with multiple high-torque servos, 

you should use a current and voltmeter (HAN172). Plug the voltmeter in an 

open channel port in the receiver and, with the system on, load the control 

surfaces (apply pressure with your hand). Monitor the voltage at the receiver. 

The voltage should remain above 4.8 volts even when all servos are heavily 

loaded. The optional Flight Log has a built-in voltmeter and can be used. 

2. With the current meter in line with the receiver battery lead, load the 

control surfaces while monitoring the current. The maximum continuous 

recommended current for a single heavy-duty servo/battery lead is three 

amps. Short duration current spikes of up to five amps are acceptable. 

If your system draws more than these currents, you should use multiple 

packs with multiple switches and multiple leads plugged into the receiver. 

While a JR receiver’s minimum operational voltage is 3.5 volts, you should 

test the system to a minimum acceptable voltage of 4.8 volts during ground 

testing. This provides headroom to compensate for battery discharging or if 

the actual flight loads are greater than the ground test loads. 

Note: JR’s amplified Y-harness (JRPA133) is for use with Z-PCM only. JR’s 

non- amplified Y-harness (JRPA135) should be used with PPM, SPCM or 

DSM/DSM2 systems. 

3. If using a regulator, perform the above tests for an extended period of 5 

minutes. When current passes through a regulator, heat is generated. This 

causes the regulator to increase resistance, causing even more heat to build 

up (thermal runaway). While a regulator may provide adequate power for a 

short duration, you should test its ability over time. The regulator may not be 

able to maintain voltage at significant power levels. 

4. For really large aircraft or complex models (for example 35% and larger or 

jets), multiple battery packs with multiple switch harnesses are necessary 

or, in many cases, one of the commercially available power boxes/busses is 

recommended. No matter what power system you choose, always carry out 

test #1 above. Make sure the receiver is constantly provided with 4.8 volts or 

more under all conditions.

When all channel rollers are in the MAST position, NORMAL appears on the 

display and all channels transfer to the student when the trainer switch is 

depressed. In this case, you must fully program the model in both the master and 

the slave transmitters. If the slave system is a XP9303, X9303, X9503, 11X, or 

12X, and all channel rollers are in the MAST position, you must leave the slave 

transmitter in the normal default MASTER setting. 

If one or more of the channel rollers are in the SLAV position, only the throttle, 

aileron, elevator, and/or rudder channels are transferred to the Slave transmitter 

depending on which are set to SLAV in the Master transmitter. If one or more 

of the channel rollers are in the SLAVE position, the Master controls all Dual 

and Expo rates, Gear, and flap positions, and the Slave transmitter need not be 

programmed for the model. If one or more of the channel rollers are in the SLAV 

position, the Slave transmitter should be set to SLAVE mode. 

When less than all channels are selected as SLAV, PROGRAM T appears on the 

display indicating the Trainer System is programmed to transfer only selected 

channels. 

Note: The Slave transmitter battery must be fully charged and installed and the 

power switch in the OFF position. 

1 Rotate the roller to highlight INH under SW SEL in the lower left corner.

will remain transferred until you release the trim lever. 

11X USED AS SLAvE 

If the Master transmitter has one or more of the channel rollers in the SLAV 

position, highlight and select MASTER. The display switches to SLAVE. A 

message appears instructing to Connect DSC & POWER off. Make sure the 

transmitter power switch is OFF and the Trainer cord connected between the two 

transmitters. 

The 11X is now ready to use as the Slave with one or more channels selected in 

the Master transmitter to SLAV. 

If the Master transmitter has all channels set to MAST, leave the Slave 

Transmitters’ Trainer System set to the Default MASTER setting. In this case, 

you must fully program the Slave transmitter and set it up to fly the model. All 

programming of the Slave transmitter will be used. Plug the Trainer cord into the 

back of the transmitter leaving the power switch in the OFF position. 

Your 11X is ready to use as the Slave with all channel rollers in the Master 

transmitter set to MAST.

FLIGHT MODeS (AIRPLANe) 

A Flight Mode represents an aircraft configuration (Dual Rate/ Expo, program 

mixes, Aileron Differential, Flap System, Gyro System, etc.) that allows you to do 

different things by flipping a single switch. Up to 3 flight modes are available in 

the 11X. 

Programming Flight Modes allows you to select a switch position to activate a 

collection of settings optimized to perform a maneuver. For example, you can 

set up an aerobatic aircraft so the Flight Mode switch in its 1st position (FM 

0) configures the aircraft for precision flying; the 2nd position (FM 1) sets the 

aircraft up for snap rolls; and the 3rd position (FM 2) sets the aircraft up for 

aggressive 3D flight. Flight Modes could just as easily represent aircraft settings 

for Take Off, Flying, and Landing for a turbine-powered jet aircraft. 

Most of the functions found in the 11X that are switch selectable including 

programmable mixers, throttle curves, differential, gyro settings, servo speed, 

etc. can be assigned to one or more Flight Modes. This allows up to 3 completely 

different aircraft configurations selectable in-flight using one of six 3-position 

switches (Flight mode switch, Rudder D/R switch, Flap switch, Elevator D/R 

switch, Aux 2 switch, Aileron D/R switch, or Inhibit). 

You can select and activate Flight Mode switches in the Device SEL function in 

the System menu. Once Flight Modes are activated, you have a choice of using 

the Flight Mode switch to select up to 4 Dual Rates and Exponential settings 

for each of the primary controls (ELEV, AILE, RUDD), or you can control Dual 

Rates and Exponential settings by the 3 individual Dual Rate switches. All other 

functions activated by a switch can be assigned to 1 or more Flight Modes when 

Flight Modes are activated. 

To Activate flight Modes 

1 From System List, highlight and select Device Select using the Roller. 

2 In the Device Select function, using the Roller, highlight and select INH 

next to FLIGHT MODE. When selected, 7 options appear: (Flight Mode SW, 

Rudder D/R SW, Flap SW, Elevator D/R SW, Aux 2 SW, Aileron D/R SW, 

or INH). Highlight and select the desired flight mode switch. Alternatively, 

once the flight mode switch selection screen is open, you can utilize the 11X 

Auto Assign switch function; move the switch you want to use as the flight 

mode switch to select it. The switch can be any of the 3-position switches. 

SWITCH ASSIGNMENTS 

The 11X allows you to change the standard default switch assignments for the 

GEAR, FLAP, AUX2, AUX3, AUX4, AUX5, and AUX6 channels. Changing the 

switch assignments is a matter of preference. 

To Change One or More Switch Assignments 

1 In the Device Select function, use the Roller to highlight and select the 

desired channel to the right of GEAR, FLAP, AUX2, AUX3, AUX4, AUX5 or 

AUX6. 

2 A list of available switches displays. Highlight and select the desired switch 

with 3. In this selection screen, you can also set the 2 top trimmers to work 

as 2-position switches, 3-position switches, or as momentary switches for a 

selected channel. 

3 Repeat for as many switches as desired. 

ACTIvATE/INHIbIT CHANNELS 

The 11X allows you the ability to activate, inhibit or program channels 5 (Gear), 7 

(Aux2) and 8 (AUX 3) to operate as a Gyro or Pitch function. 

Note: Inhibiting a channel is necessary when auxiliary channels are used as 

dual primary flight controls, such as using 2 channels/servos for 2 Ailerons or 2 

servos/channels to operate the Elevator or Rudder. In this instance, the Elevator 

and Rudder sticks operate the auxiliary channels. You should inhibit the auxiliary 

switches in the Device Select function. 

Note: If any of the channels identified above as a 2nd channel for a primary flight 

control (AILE, ELEV, RUDD, FLAP), be sure to Inhibit (INH) the switches for the 

channels in this function or they will not be available to use as a second control 

channel. 

1. If using GEAR, FLAP, AUX2, AUX3, AUX4, AUX5 or AUX6 as a 2nd primary 

flight control, inhibit the corresponding switch by highlighting ACT along 

the right side of the display. Press the roller to select INH. 

Note: When SYS appears next to FLAP, the FLAP SYSTEM function will appear 

in the Function List (described later). If the aircraft is equipped with flaps, or 

equipped with Flaperons that are actually going to be used as flaps then SYS 

should be set next to FLAP. 

Note: When GYR appears, the Gyro Function appears in the Function List 

(described later on page 27). Two gyro programs are available. 

Note: When PIT appears, the Pitch Function appears in the Function List 

(described later on page 22, 26).

WING TYPE 

The Wing Type function provides for 4 different wing types (NORMAL, 

FLAPERON, DELTA and 4- Aileron). Use NORMAL wing type when using only 

the Aileron channel to control ailerons, either with 1 servo, or multiple servos 

connected through a Y-harness to the aileron channel. 

Use FLAPERON typically when each Aileron is controlled by a separate servo 

on separate channels and the aircraft has no other flaps. Setting the wing type to 

FLAPERON also makes the Differential and Elevator-to-Flap mixing functions in 

the Function List available. 

The Wing Type function contains the Twin Engine (Twin E.) feature, allowing 

you to set up a 2nd throttle channel for a second engine, complete with its own 

independent sub- trim, travel adjust and separate trims and throttle curves. 

Use DELTA for Delta wing aircraft (Elevon). With Delta wing type, the Ailerons and 

elevator are mixed giving roll and pitch control for Delta wing airplanes. 

4-AILERON is used in aircraft where two servos operate the right aileron and two 

servos operate the left aileron. In this configuration each servo is independently 

adjustable for sub-trim and travel adjust. 

Note: Dual ailerons is a function commonly employed for aircraft using two 

servos and two channels to operate the Ailerons. It provides the ability to utilize 

Aileron Differential and allow precise independent adjustment of sub-trim and 

travel adjust for each aileron. 

If the aircraft has flaps separate from the Ailerons, Dual aileron wing type and the 

activation of dual flaps is recommended. 

v-TAIL MIX 

The Wing Type function provides programming for aircraft that have a V-Tail 

configuration where the 2 tail control surfaces are used for both Elevator and 

Rudder control. 

DUAL CONTROL fUNCTIONS 

Wing Type allows you to activate Dual Aileron, Dual Elevator, Dual Rudder and 

Dual Flap. Use this function when two servos are driving the primary control 

surfaces allowing the independent adjustment of sub-trim and travel adjust of 

each channel. 

Note: To access Dual Flaps it is necessary to assign the Flap to SYS (system) in 

Device Select. When Dual Flaps are activated, Aileron-to-Flap mixing becomes 

available in the function list (page 25). 

TO PROGRAM A WING TYPE 

1. Highlight and select Wing Type in the System List using the roller. 

2. Highlight Wing then select the wing type appropriate for your aircraft. 

Normal- If using only the Aileron channel to control both ailerons, with a single 

servo or with two servos connected together via a Y-harness, you should select 

the NORMAL wing type. Also use NORMAL if the aircraft has flaps separate from 

the ailerons. If using two aileron channels, activate the Dual aileron channel listed 

below. 

flaperon- If using two channels to control the Ailerons and the aircraft does not 

have separate flaps, select FLAPERON as the wing type. Plug the right Aileron 

into the Aileron channel (CH2) and plug the left Aileron servo into the FLAP or 

AUX1 channel (CH6) of the receiver. 

Note: If using the ailerons as flaps, inhibit the FLAP Switch and FLAP TRIM in 

the Devic.SEL function in the SYSTEM Menu. This eliminates having a severe 

out-of-trim condition if the FLAP Switch is accidentally moved. 

DELTA- If you have a Delta wing aircraft then select DELTA in wing type. This 

mixes the aileron and elevator functions to provide roll and pitch control for these 

types of aircraft. Plug the right control surface into the aileron channel (CH2) and 

plug the right surface into the elevator channel (CH3). 

4-Aileron- If your airplane is equipped with two servos for the right aileron and 

two servos for the left aileron, select the 4- Aileron option. Right aileron servos 

plug into channels 2 and 7. The left aileron servos plug into channels 5 and 8. 

Each servo is independently adjustable for sub-trim and travel adjustment and the 

digital trim is active for all servos. 

If the aircraft 0has a V-tail configuration, highlight INH next to V-tail in the 

Wing TYPE function and press the roller until ACT appears. Plug the right 

Elevator servo into the Elevator channel (CH3) and plug the left Elevator servo 

into the Rudder channel (CH4). 

DUAL CHANNELS 

1 To assign a 2nd channel to Ailerons, Elevator, Rudder or Flaps, highlight 

and select INH under the desired channel on the Mate line of the Wing Type 

display. A list of available channels displays. 

2 Highlight and select the channel to be the Slave to the control channel 

represented above it. Plug the 2nd control surface servo into the channel 

selected as the Slave. 

3 INH appears on the Trim Line of the display directly beneath the channel 

just selected. This means the corresponding digital trim (FLAP TRIM or 

AUX TRIM) located next to the FLAP and AUX2 switches can be used as 

additional trims. 

However, additional trims do not function in the same fashion as regular trims. 

Instead, they trim the controls so that both channels move in the same direction 

– like reflexing both Ailerons or in the case of Elevator halves, the Elevators 

would move in opposite directions. As a result, these additional trims should 

remain inhibited unless there is a special need for them. If changed to ACT, the 

corresponding trim switch (Right Trimmer or Left trimmer) becomes active. If set 

to INH these additional trim switches are inactive. Normal trims continue to work 

regardless of the settings. 

TWIN ENGINE 

If the aircraft is equipped with twin engines, you can use the Twin Engine feature 

(Twin E.) for a second throttle channel with an optional separate digital trim. 

FLIGHT MODeS (HeLICOPTeR) 

The 11X allows you to assign flight modes to any three-position switch. The 

system defaults with the flight mode on the flight mode switch (upper left corner 

of transmitter). In most cases this position is recommended. 

To Assign the flight Mode to a Switch 

1 In Device Select highlight and select FMOD. A screen appears that allows 

you to move the Flight Mode to the Rudder Dual Rate Switch, Ail D/R, ElE 

D/R, Aux 2, Flap SW or the Flight Mode switch. 

2 Using the roller, select the desired flight mode switch position. Alternately, 

when you have the flight mode switch options displayed, move the switch 

you would like to use as the flight mode switch. The system automatically 

sets that switch to be the flight mode switch. 

ACTIvATING EXTRA fLIGHT MODES 

3 AND 4 

The 11X offers up to 6 separate flight modes. The system defaults to offer 4 flight 

modes (N, 1, 2, Hold). There are 2 additional flight modes, numbered 3 and 4 

you can activate through the Device Select function. 

To Activate 2 Additional Flight Modes (Flight Modes 3 and 4) 

1 In the System List highlight and select Device Select. 

2 Highlight and select INH under the word EXTRA using the Roller. When 

selected, a screen appears allowing the various switch options. Highlight 

and select the switch you want to access Extra Flight Modes. Alternately, 

once you have the Extra Flight Mode switch options displayed, move 

the switch you want to use as the Extra Flight Mode switch. The system 

automatically sets that switch to be the extra flight mode switch. 

Once Extra Flight Modes have been activated, two additional sets of Throttle and 

Pitch curves numbered 3 and 4 appear in Function Mode. 

SWITCH ASSIGNMENTS 

The 11X provides the ability to change the standard default switch assignments 

for the GEAR, AUX2 through AUX6 channels and the high pitch trim. The switch 

positions are defaulted to the most common positions, however, changing the 

switch assignments (positions) is a matter of preference. 

To Change One or More Switch Assignments 

1 In the Device Select function, use the Roller to highlight and select GEAR, 

AUX2 through AUX6 channels. 

2 Once a channel is selected, a list of available replacement switches is 

displayed. Highlight and select the desired switch with the Roller. 

3 In this selection screen, you can also set the 2 top trimmers to work as 

2-position switches, 3-position switches, or as momentary switches for a 

selected channel. 

4 Repeat for as many switches as desired. 

ASSIGNING/ACTIvATING GOvERNOR 

AND GYRO fUNCTIONS 

The 11X Device Select program allows you to activate and assign the Governor 

and Gyro functions to one of the following channels: GEAR, AUX2, AUX3. 

Note: The Governor function defaults to Inhibit and is not available until the 

function is activated in Device Select. You can also inhibit Gyro or set it to 

channels GEAR, AUX2 or AUX3. 

If U5sing te Governor or Gyro Functions 

1 Highlight INH next to GEAR, AUX2 or AUX 3. Press the Roller to access INH, 

ACT, GOV or GYR. 

2 Use the roller to select the desired function. 

DEACTIvATING CHANNELS 

The 11X provides the ability to inhibit a number of channels. This is useful when 

auxiliary channels are used for mixing. In this instance, the switch no longer 

operates the channels allowing them to be used as slave channels. Also, the 

deactivated channels assume a centered (1.50ms) position needed for mixing. 

1 If using GEAR, AUX2 through AUX6 as slave channels, inhibit the 

corresponding switch by highlighting ACT along the bottom line of the 

display. Then press the Roller until INH appears under the switches you 

want to turn off. 


17

SWASHPLATE TYPE 

The Swashplate Type function enables the 11X to operate six different types of 

swashplate control systems. The Swashplate options are: 

• 1 Servo NORM standard mechanical mixing type 

• 2 Servo/180° 

• 3 Servo/120° CCPM (most popular) 

• 3 Servo/140° CCPM (JR Vibe 50/90SG) 

• 3 Servo/90° CCPM 

• 4 Servo/90° CCPM 

To Select a Swashplate Type 

1. In the System Menu, highlight and select Swash Type using the Roller. 

2. Highlight and select the displayed swashplate to access the available 

swashplate types. 

3. Select the desired swashplate. 

FLIGHT MODeS (SAILPLANe) 

A Flight Mode represents an aircraft configuration (camber position, trim 

positions, Dual Rate/Expo settings, program mixes, aileron differential value, 

etc.) that is programmed to optimize the aircraft for a particular task. Up to 5 flight 

modes are available in the 11X that include Launch, Normal, Reflex, Thermal and 

Float. 

The objective of programming Flight Modes is to provide the ability to select a 

switch position to activate a collection of settings that are optimized to perform 

a particular task. For example, the launch mode is typically set up to give the 

following: 

• The flaps and flaperons are preset with positive camber to give more lift 

during launch. 

• An elevator preset trim position that gives the best climb is programmed. 

• A high rudder rate with reduced exponential to give authoritative steering 

control on launch is desired, while the elevator and aileron rates are set to 

give a medium response. 

• Aileron-to-rudder mix is turned off, as are landing flaps and elevatorto-flap 

mix. Camber adjustment of the side lever is programmed to give 

proportional camber changes to allow for last minute adjustments based on 

wind and winch conditions. 

• Aileron differential is set at 50%. 

You can select all programming parameters by moving one switch. You can 

assign most of the switch-selectable functions in the 11X to one or more Flight 

Modes. Some of these functions include: Flaperon Mix, Servo Speed, Camber 

system, Differential, Aileron to rudder mix, Elevator to flap mix, Flap rate, Brake 

system, trims and programmable mixes. This provides the ability to have up to 

5 completely different aircraft configurations that are selectable in flight using 

switches. 

When 3 Flight Modes are activated, you can select them during flight by using 

one of seven 3-position switches: Flight mode switch, Motor switch, Butterfly 

switch, Rudder D/R switch, Elevator D/R switch, Aux 2 switch, Aileron D/R switch 

or Inhibit. 

To activate the 2 Extra flight modes, the 4th and 5th flight modes are assigned 

to one of the following switches: Flight Mode, Rudder D/R switch, Elevator 

D/R switch, Flap Switch, Aux 2 switch, Aileron D/R switch, Inhibit. Flight mode 

switches are selected and activated in the Device SEL function in the System 

menu. Once Flight Modes are activated, you can use the Flight Mode switch to 

select up to 4 Dual Rates and Exponential settings for each of the primary controls 

(ELEV, AILE, RUDD). But you can continue to control Dual Rates and Exponential 

settings by the 3 individual Dual Rate switches. You can assign all other functions 

that can be activated by a switch to 1 or more Flight Modes when Flight Modes 

have been activated. 

ACTIvATING AND ASSIGNING 

PRIMARY fLIGHT MODES 

In the factory default setting, all flight modes are inhibited. Flight modes are 

activated and assigned to the desired switch position using the REFLEX and 

LAUN functions in the Device SEL screen. 

In system mode list rotate the Roller until Device SEL is highlighted. Press the 

Roller to access the Device Select screen. 

To activate the launch, normal and float mode, rotate the Roller until LAUNCH is 

highlighted then press the Roller. The following screen appears: 

At this point, you must decide which 3-position switch you prefer to assign the 

flight mode to. When a 3-position switch is selected, launch, cruise and land 

will be activated. We recommend starting with the Flight Mode Switch (left 

top 3-position switch), as this is a convenient place. Rotate the Roller until the 

desired switch is highlighted; press to select. Alternatively, once you have the 

switch options displayed, move the desired switch to automatically select the 

switch.

flight mode. Highlight the desired flight mode position to edit under AUTO and 

push the roller down to select. Select the desired D/R and EXP setting for that 

control surface for the selected flight mode (P0 through P3). Each primary control 

(Aileron, Elevator, and Rudder) has its own AUTO setting. This allows the rates to 

be different for each flight mode and each primary control surface. 

TRAvEL ADJUST 

Travel Adjust allows for independent adjustment of each direction of servo travel. 

To Program Travel Adjust values 

1. Highlight and select Travel ADJ. in the Function List to obtain the Travel 

Adjust display. 

2. Use the Roller to highlight and select each channel. Adjust the travel in each 

direction by rotating the Roller. To change the direction of travel, move the 

stick/switch/lever in the desired direction to highlight L/R, U/D or +/-. 

LIMIT ADJUST 

The Limit Adjust function allows the adjustment of the maximum travel possible 

for each channel in independent directions. This prevents any channel from 

being overdriven on the model as limit adjust overrides features like Travel 

Adjust, Dual Rates, and any programmable mixes. 

To Program Limit Adjust values 

1. Highlight and select Limit ADJ. in the Function List to obtain the Limit 

Adjust display. 

2. Use the Roller to highlight and select each channel. Adjust the travel in each 

direction by rotating the Roller. You can change the direction of travel by 

moving the stick/switch/lever in the desired direction to highlight L/R, U/D, 

or +/-. 

SUb-TRIM 

Use Sub-Trims to fine-tune the output alignment of the servo arms. 

To Program Sub-Trim Values 

1. Highlight and select Sub-Trim in the Function List to obtain the Sub-Trim 

display. 

2. Highlight and select the channels you want to adjust. Once a channel is 

selected, rotate the Roller until the servo arm is in the desired position. 

SERvO REvERSING 

The servo reverse function allows the direction of each servo to be selected. 

To Program Servo Reverse 

1. Highlight and select Reverse SW in the Function List to obtain the servo 

reversing display. 

2. Use the Roller to highlight and select the channels to reverse. Pressing the 

Roller toggles the channel between Normal and Reverse. 

Note: Your aircraft manual may refer to this as changing transmitter flight control 

directions in the Control Test/Reverse Controls section. 

SERvO SPEED 

The 11X allows you to adjust the speed of servos on each channel in each 

direction. You can reduce the speed (servo slowed) from its normal speed. 

However, the function cannot cause a servo to move faster than its rated 

specifications. Each servo can have 2 sets of speeds in each direction that are 

Flight Mode or switch selectable. 

The servo speed function is useful for scale models with retractable landing gear 

and gear doors. In many instances, the need for gear door sequencers can be 

eliminated. If the gear door servos move at normal speed and the landing gear 

servos move at a slower speed when the gear is lowered, the gear doors will be 

open before the landing gear begins to come down. In the opposite direction, if 

the gear door servos move slowly and the landing gear servos move at normal 

speed, the gear can retract before the gear doors begin to close. 

Note: Many retract servos are non-proportional and simply move from endpoint 

to endpoint. Such servos are not adjustable in the servo speed function. 

To Adjust Servo Speed 

1 Highlight and select Servo Speed in the Function List to obtain the Servo 

Speed display. 

2 Select SW SEL and push the roller down to access Switch Select. If you only 

want one servo speed, then all selectable switch positions in this screen 

should be P0. If you want two servo speeds, assign the desired switch to 

change the servo speed to P1. Return to the main screen. 

3 If you want a single set of servo speeds, make sure the display shows Pos0. 

If it does not, select Pos1 and change it to Pos0. Highlight and select the 

channel and direction for each servo to be adjusted. 

After you select a direction for a servo, you can set the servo speed. With 

the 11X, servos can travel from .176 seconds for 60 degrees of rotation to 

15.0 seconds for 60 degrees of rotation. Adjust the speed of each servo until 

obtaining the desired speed. 

4. If you want 2 sets of servo speeds that are Flight Mode or switch selectable, 

set one set of values to NORM for all channels. You can turn off the slowing 

of servos by selecting the position (Pos0 or Pos1) with the NORM values. 

Highlight and select Pos0 and change it to Pos1. Highlight and select the 

channel and direction for each servo you need to adjust. 

When you select a direction for a servo, you can set the servo speed so the 

servo travels at the desired slower rate. Switch between Pos0 and Pos1 to 

view and adjust the 2 sets of values for each servo. 

Note: Pos1 always has priority over Pos0. In other words, if you select 

multiple switches and one is in its Pos1 position, all other switches are 

ignored and the Pos1 values are in effect. 

THROTTLE CURvES 

Programmable throttle curves allows you to manipulate the throttle response 

(stick position vs. throttle output), optimizing it for various maneuvers like torque 

rolls. You can adjust programmable throttle with the Throttle Curve function. Two 

programmable throttle curves are available- Pos0 and Pos1. 

If you activated the Twin E. function in Wing Type (page 15-16 for twin-engine 

aircraft), independent throttle curves are available for each engine to help 

eliminate discrepancies in rpm between the two engines at all throttle positions. 

To Program a Throttle Curve 

1 Highlight and select Thro Curve in the Function List and press YES or NO to 

access the throttle curve function. 

2 If you need to have 2 throttle curves, use the Roller to highlight SW SELECT 

and a list of available Flight Modes and switches appears. Select the Flight 

Mode(s) (FM0, FM1, or FM2), switches and/or switch position (SPS) 

desired to select between the 2 curves. Highlight and select Pos0 to toggle 

between the Pos0 and Pos1, in order to display and adjust the 2 curves. 

Note: If you activated Twin E. for a twin engine aircraft, there will be a Pos0 

and Pos1 for both the right and left engines, providing a total of 4 possible 

throttle curves. However, they are named RTH.0, RTH.1, LTH.0, and LTH.1. 

They represent Right Throttle Pos0 & Pos1 and Left Throttle Pos0 & Pos1 

respectively. 

3. Highlight EXP and select it to turn exponential ON if desired. This will 

smooth out the throttle curve. 

4. Highlight the desired point (L, 1, or H) and press the roller to access the 

output value. Rotate the roller to change the output value. Repeat for all 

desired points. (The graphic display will change with your input to represent 

the new point position.) 

5. To store a new point move the throttle stick until add appears on the lower 

left side of the screen. When the desired position is achieved press the add 

button and the point will be stored onscreen. You can store up to seven 

points. 

6. To adjust access Pos1 throttle curve (only available when SW is assigned to 

a switch) highlight Pos0 and rotate the roller to access Pos1. Repeat the step 

above to adjust Pos1 throttle curve. 

7. To adjust the throttle trim authority, highlight the TRIM using the roller and 

rotate to select a trim authority value of 0 100%. Note the graphic display 

changes to represent the new trim authority. 

8. THRO STK allows you to use the throttle stick to switch from Pos0 throttle 

curve to Pos1 throttle curve. To program a throttle curve Pos change with 

the throttle stick, highlight the INH under THRO STK and adjust the values 

using the throttle stick to select the point at which the throttle stick will 

change between the 2 programmed throttle curves. Afterwards, press store 

to save the position 

THROTTLE CURvES 

The 11X offers up to five (5) separate throttle curves with up to eight adjustable 

points per curve. This function allows you to customize the throttle curve to 

maximize engine performance at any particular pitch setting. Once the throttle 

curves are established, you can activate each in flight using the 3-position flight 

mode switch. If you activated the additional 2 flight modes (numbers 3 and 4) 

in Device Select, you will use an additional switch to activate these modes. Two 

additional throttle curves will be available. 

The flight mode switch offers three selectable positions: 

• N=Normal 

• 1=Stunt 1 

• 2=Stunt 2 

• 3=Stunt 3 (optional) 


The N (Normal) position is used as the hover throttle curve. 

Positions 1 and 2 (Stunt 1 and Stunt 2) are typically used for forward flight and 

3D maneuvers. Optional flight modes 3 and 4 are also designed for use with 

aerobatic maneuvers and forward flight. 

Note: The throttle trim and hovering throttle trimmer are only operable when the 

flight mode switch is in the normal position. In the 1, 2, 3, 4 or hold positions, 

these two functions have no effect. Also, adjusting the hovering throttle trimmer 

and throttle trim has no effect on the input values of the throttle curve. Each of the 

eight points of the throttle curve is independently adjustable from 0–100%. 

Accessing the Throttle Curve function 

1. In function mode use the Roller to highlight the Thro Curve function, then 

press to access. ALL SERVOS HOLD ? will display. Press YES or NO to 

access the throttle curve screen. 

2 Move the flight mode switch to the desired position to select the flight mode 

you will program. The flight mode will display in the upper left corner of the 

screen. 

3 Move the Roller and highlight the desired throttle point to be adjusted. Press 


21

the Roller to access the point value, then roll the Roller to increase and 

decrease the point value. 

4. To set throttle curves for flight modes, switch the flight mode to the desired 

position; the screen will change to that flight mode. 

5. Highlight the pitch point you want to adjust and press the roller. Rotate the 

roller to adjust that point on the pitch curve. 

6. To add a point move throttle stick to the desired position until STOR appears 

on the left bottom of the screen. Pressing STOR will save a new point at that 

position. 

Note: To eliminate a point, press ERAS (bottom left of the screen) when the point 

is highlighted. 

PITCH CURvE 

The Pitch Curve controls variable pitch propellers. The Pitch function works 

nearly identically to a programmable curve mix, allowing you to store and adjust 

up to 7 points throughout the curve. Two curves are available (Pos0 and Pos1) 

and are selectable with various switches, flight modes, throttle position or Stick 

positions (SPS). An Exponential function is available that smoothes the pitch 

curve. Pitch must be assigned to Gear, Aux2 or Aux 3 channels in Device select 

to access the Pitch function. The Pitch curve mixes the throttle channel to the 

channel selected as PIT in the device select mode. 

POINT NAMES/NUMbERS 

The points you adjust list vertically by name (Point-L, 1, 2, H, etc.) and display by 

number on the graph. 

Change the value of a point by highlighting and selecting the point name and 

adjusting the desired percentage. 

CURRENT POINT SETTING 

This list shows the setting for each of the 7 adjustable points (Point-L, 1, 2, 3, 4, 

5, H). The value of each point determines where the point positions vertically on 

the graph, dictating the Pitch servo position relative to the throttle. You can set the 

point values be from 0 to +100. 

To change a point value, highlight and select the Point Name to the left of the 

point value, then adjust the desired value. 

To reset original settings, highlight a point value then press CLR. 

vERTICAL LINE 

The vertical line on the graph shows the current throttle channel position. When 

the throttle channel is turned fully in one direction, the line is to the extreme left 

over Point-L. When it is at neutral, it is centered over Point-1 and when fully 

deflected in the other direction, the cursor is at the extreme right of the graph 

over Point-H. Where the vertical line intersects the Curve/Line over a given point 

defines the pitch servo’s position, which is equal to the value assigned to that 

point. 

GRAPH 

The graph illustrates the pitch curve. The X-Axis (horizontal plane) represents 

throttle channel movement. The Y-Axis (vertical plane) represents the Pitch servo 

movement. 

POINTS YOU CAN ADD AND ADJUST 

The Pitch Curve defaults to three points (L, 1 and H). You can add up to four 

additional points. To add a point, move the throttle stick in the desired position 

until STOR appears on the left bottom of the screen. Press STOR to save a new 

point at that position. 

Note: To eliminate a point, highlight it then press ERASE (bottom left of the 

screen). 

EXPONENTIAL 

The Exponential function blends the Curve between the points on the graph 

to provide a smooth response. It defaults to OFF. To turn it on and smooth the 

mixing curve, highlight and select OFF. It will toggle to ON. 

PITCH CHANNEL POSITION 

The Pitch servo position next to OUT at the bottom left of the screen displays in 

values from 0 to +100. It represents the servo travel corresponding to the present 

Throttle Channel position. 

THROTTLE CHANNEL POSITION 

The Throttle channel position appears on the bottom line of the display next to IN. 

It displays in values from 0 to 100 with 50 being the center or neutral position. It 

represents the present Throttle channel position. 

SWITCH SELECT 

There are numerous switches that can switch between Pos0 and Pos1. Note: If the 

upper and lower settings for Pos0 or Pos1 are left at 0% the mixer can be turned 

on and off with the switch. In addition, if Flight Modes are activated in the Device 

Select function, flight mode switches may be selected. Also you can use Switch 

positions (SPS) to select between Pos0 and Pos1. 

To choose a switch that selects between the Pos0 and Pos1 values, highlight and 

select the switch name. It will toggle between Pos0 and Pos1. 

fLAP SYSTEM 

The 11X features a three-position Flap System with Elevator and Aileron 

compensation, programmable Delay, and an Auto Land feature. It allows you to 

program the flaps to three different positions, normally full flap, half flap and no 

flap or fully retracted position. 

Note: The Flap System is available in the Function List only if SYS is selected on 

the OUT line next to FLAP in the Device Select function in the System List. 

Because flaps generally cause a change in pitch (Elevator trim), the Flap System 

provides for setting an Elevator deflection for each flap position. This is called 

Elevator Compensation. 

There is also a programmable Delay in .1-second increments up to a maximum 

of 2 seconds. The Delay determines how long it takes for the Flaps and Elevator 

to reach their positions. This delay function ensures the Flaps and Elevator 

reach their positions at the same time resulting in smooth Flap deployment and 

retraction with minimal pitch change. 

The Auto Land feature, if implemented, automatically retracts the Flaps and 

Elevator compensation when the throttle is raised above a specified throttle 

position. This is useful during a missed landing approach when a go-around 

is required. The Flap System allows the Flaps to deploy using the Flap Switch, 

Flight Mode switch or a combination of both. 

To Program the flap System 

1. Highlight and select Flap System in the Function List to obtain the Flap 

System display. 

2 If using Auto Land, scroll to INH under AUTO THRO and select it with the 

Roller. INH changes to 0 when selected. 

3 Move the Throttle Stick between 0–100% to select where the Auto Land 

feature is to retract the Flaps and Elevator compensation. The press STO at 

the lower left corner of the screen to store the value. 

We recommend the throttle position be set very high at first (between 90–99%) to 

give the aircraft a chance to regain some speed before the Flaps actually retract. 

As the Flaps retract, lift decreases and the stall speed of the aircraft increases 

and may cause a crash if airspeed is too low. When there is a missed approach, 

advance the throttle slowly up to about 90% and wait until the aircraft picks up 

some speed before advancing the throttle to full, causing the Flaps to retract. 


23 

fLAP 

The FLAP values correspond with how far the flaps deflect when in the NORM, 

MID, and LAND positions. Generally the NORM position represents normal flying 

where the flaps are fully retracted. The MID position is typically used for half flaps 

and LAND for full flap for landing. 

1. With the Flap switch in its uppermost (Normal) position (no flaps deployed), 

scroll to the NORM parameter under FLAP on the display. Select the value 

with the Roller and adjust its value to bring the flaps to their normal flying 

position (no flaps deployed.) 

2. With the Flap switch in the MID position, scroll to MID under FLAP on the 

display and select it. Adjust the desired percentage to deflect the flaps to the 

desired amount. 

3. Put the Flap switch in the lowermost LAND position. Scroll to LAND under 

FLAP on the display and select it. Adjust the percentage to deflect the flaps 

to the desired position. 

eLeV – eLeVATOR COMPeNSATION 

The ELEV values represent the Elevator deflection that occurs when the Flaps are 

deployed to their various positions. It requires some trial and error to attain the 

exact values. Once properly adjusted, the aircraft will assume the proper pitch 

attitude for all flap positions. 

1. Adjust the Elevator compensation values (ELEV) as desired for each switch 

position as you adjusted the flaps above. 

AILe – AILeRON COMPeNSATION 

The Aileron values represent the Aileron deflection that occurs when the Flaps 

are deployed to their various positions. It requires some trial and error to arrive at 

the exact values. Once properly adjusted, the aircraft will assume the proper roll 

attitude for all flap positions. 

1. Adjust the Aileron compensation values (AILE) to the desired values for each 

switch position you adjusted the flaps above. 

fLIGHT MODES 

If you activated Flight Modes in the Device Select function, FM0, FM1 and FM2 

appear along the right side of the Flap System display representing the 3 Flight 

Modes. You must assign each of the Flight Modes one of the Flap values (NORM, 

Mid, or Land). When that Flight Mode is selected during flight, the Flaps deploy 

to that position. SW is also an option. When SW is selected, flap operation is 

controlled by the Flap switch when in that Flight Mode. 

If you did not activate Flight Modes, skip this portion of the Flap System. 

1. For each Flight Mode, highlight and select FM0-FM2 and select either a 

flap position (NORM, Mid, Land) for the flaps to assume when in that Flight 

Mode, or select SW for the Flap switch to control the flaps.

DELAY 

The Delay feature determines how long it takes for the flaps and Elevator to reach 

their positions. When the delay function is programmed, the 11X automatically 

times the Flaps and Elevator to reach their positions at the same time, resulting in 

smooth Flap deployment with minimal pitch change. The Delay is adjustable in 

.1-second increments up to a maximum of 2 seconds. 

1. Highlight and select Delay in the Flap System display using the Roller. Then 

use the rotary to select a delay between .1- second and 2 seconds. 

SNAP ROLL 

The 11X has a Snap Roll system that can combine the Snap Roll switch with 

Flight Modes to select a direction (Right/Up, Right/Down, Left/Up, and Left/ 

Down) and the amount of deflection for Aileron, Elevator and Rudder. You can 

program up to four directions and corresponding rates and assign a Direction/ 

Rate combination to 1 or more of the 3 Flight Modes. Press the Snap Roll switch 

for the aircraft to snap roll in the direction of the rates assigned to the Flight Mode 

currently selected. 

You can program a Snap Roll stick switch position (STICK POS) that causes all 

channels to default to the programmed snap roll position when the selected stick 

is displaced further than the programmed position. 

If you activated Flight Modes, up to 3 Snap Roll directions/rates can be assigned 

—one per Flight Mode. If Flight Modes have not been activated then only one 

direction/rate is available per snap roll (4 available). The Snap Roll function is 

inhibited as a default and must be turned on in order to use it. 

If the Snap Roll function Is To be Used 

1 Highlight and select Snap Roll in the Function List. Select INH to activate a 

single snap roll select S.ROLLØ. 

2 Scroll to the desired channel and set it to a desired value. 

3 Repeat step 2 for the other channel’s values. 

4 Scroll and select the (+/-) to reverse the direction for each channel. 

5 If more than one snap direction/value is desired highlight S.ROLLØ to 

access the snap roll 0 thru 3 and repeat the above steps for each snap roll. 

6 To set a Stick position to enter Snap Roll, highlight and select INH for the 

channel desired. Either use the Roller to set the value, or move the selected 

control stick to the desired position to enter a Snap Roll. Press the STO key 

on the lower left. Repeat for any other stick positions to enter a Snap Roll as 

desired. Highlight and select the (+/-) to reverse the stick direction. 

NOTICE: Use this feature with extreme caution as it will cause the aircraft 

to snap roll at any selected stick position. For safety, you should use it in 

conjunction with flight modes so that in one or more flight modes this is 

selected to off. This prevents the aircraft from snap rolling with any stick 

position. 

7 If Flight Modes are active, you can turn each Snap Roll ON or OFF in each 

Flight Mode. Highlight and select the Flight Mode desired to turn the Snap 

Roll function ON or OFF in each Flight Mode. 

8 Highlight and select INH in the lower right corner of the screen under SNAP 

SW. Roll to select the LTRM or RTRM to activate the Snap Roll on either the 

Left or Right Trimmers. 

DIffERENTIAL 

The 11X Differential function reduces the Aileron travel that deflects downward 

without affecting the Aileron that travels upward. Therefore, it can eliminate 

swerving tendencies in rolling maneuvers. Differential is also available for the 

Rudder and Flap channels if you selected Dual Rudder and/or Dual Flap in the 

Wing Type menu. 

Note: Differential is available in the Function List only if the FLAPERON, Delta 

or 4-Aileron is selected in the Wing Type function in the System List or a Dual 

channel has been assigned to ailerons, flaps, or rudder in the Wing Type function. 

The Differential function provides for 2 differential settings that are switch or 

Flight Mode selectable – Pos0 and Pos1. 

To Use the Differential function 

1. Highlight and select Differential in the Function List to obtain the Differential 

display. 

2. If a single Aileron differential setting will be on all of the time, highlight and 

select Pos0 and adjust the desired percentage of differential. A positive value 

causes the downward Aileron to travel less while a negative value causes the 

upward Aileron to travel less (negative differential). 

3 If two differential values are needed, highlight SW SEL and press the roller 

to choose the desired switch(s) to select between Pos0 and Pos1 differential 

settings. 

4 Make desired adjustments to the POS 1 differential. 

Note: Pos1 always has priority over Pos0. So, if you select multiple switches 

and one of the switches is in its Pos1 position, all other switches are 

ignored and the Pos1 values are in effect. 

5 Repeat steps 1 through 4 for the Rudder and Flap channels if activated. You 

must select Dual Rudder and Dual Flap in the Wing Type menu for these 

Differentials to be available. 

AILERON TO RUDDER 

The 11X features a preprogrammed Aileron-to-Rudder mix. This mix causes 

the Rudder to deflect when the Ailerons are moved. This is useful for some 

types of aircraft that have adverse yaw, (right aileron results in a left yaw). By 

programming aileron to rudder mix in the same direction the airplane makes 

coordinated turns using ailerons only. 

To Program Aileron-to-Rudder Mixing 

1 Highlight and select AIL-RUD in the Function List to obtain the Aileron-to- 

Rudder mix display. 

2 Two sets of mixing values are available – Pos0 and Pos1. If the Pos0 values 

are left at 0% then the mixer may be turned on and off – Pos0 would be off 

and Pos1 would be on. (You can reverse this by leaving the Pos1 values at 

zero and putting values into Pos0). Highlight and select L next to Pos1 and 

set the value to give the desired amount of Left Rudder. A negative value 

reverses the direction. 

3. Highlight and select R next to Pos1 and set the value to give the desired 

amount of Right Rudder. A negative value will reverse the direction. 

4. Scroll down to the bottom line of the display to select the Flight Mode and/ 

or switch(s) to turn the mixer on and off. The example below shows Flight 

Mode 2 set to Pos1, turning on the Aileron-to-Rudder mix. You can also 

use the throttle to turn the mixer on and off. To do so, highlight and select 

THRO STK. Then set the percentage of throttle to the point where the mixer 

is switched on/off. 

Note: You can set the Pos0 values to something other than zero causing a 

different amount of Rudder deflection to occur with Aileron input. You can 

then select one or more switches to toggle between the two sets of values. 

With this setup there is always some mixing, indicated by either Pos0 or 

Pos1, and it cannot be turned off. 

AILERON-TO-fLAP MIX 

Aileron-to-Flap mix causes the flaps to move in unison with the ailerons. This 

function gives added roll response by mixing ailerons to flaps so the entire 

trailing edge functions as an aileron. 

Note: This function is only available when Dual Flap is assigned in the Wing Type 

function. 

To access Aileron-to-flap mix 

1. In the Function List rotate the Roller until AIL-FLP is highlighted. Press the 

Roller to access the Aileron-to-Flap mix. 

2. Select and enter the values in the POS0 settings if using only 1 setting. 

3. If 2 settings are desired, highlight and select SW SEL and select a switch. 

Select and enter the desired values for POS0 and POS1. 

Note: Position 1 always has priority over position 0. 

4. For the aileron trim to also function on the flaps, highlight and select INH 

next to INCLUDE AILE TRIM to change the setting to ACT. 

ELEvATOR TO fLAP 

The 11X features a preprogrammed Elevator-to-Flap mix. The mixer causes the 

Flaps (or Flaperons) to move when the Elevator is moved, resulting in tighter 

looping maneuvers, or to provide Aileron reflex for some 3D maneuvers such 

as Harriers. Typically, the flaps are set to travel downward with up Elevator and 

upward with down Elevator. The direction the flaps travel with Elevator input can 

be changed by using positive and negative values. 

To Program Elevator-to-flap Mixing 

1 Highlight and select ELE-FLP in the Function List to obtain the Elevator-to- 

Flap mix display. 

2 Two sets of mixing values are available – Pos0 or Pos1. If the Pos0 values 

are left at 0% then the mixer may be turned on and off – Pos0 will be OFF 

and Pos1 will be ON. (You can reverse this by leaving the Pos1 values at 

zero and putting values in Pos0). Highlight and select DN next to Pos1 and 

set the desired amount of Flap travel in the Down direction when full Up 

Elevator is applied. 

3 Highlight and select UP next to Pos1 and set the value to give the desired 

amount of Flap travel in the UP direction when full Down Elevator is applied. 

4 Scroll down to the bottom line of the display to select the Flight Mode(s) 

and/or switch(s) used to turn the mixer on and off. You can use the throttle 

to turn the mixer on and off by highlighting and selecting THRO STK. 

Then set the percentage of throttle to the point where the mixer is to switch 

between On and Off. 

RUDDER TO AILERON/ELEvATOR MIX 

The 11X features a Rudder to Aileron/Elevator mix that eliminatesroll and pitch 

coupling when rudder is applied. Two mixes are available and independent mix 

values can be assigned for each direction. You can use various switches, flight 

modes, the throttle stick and other stick positions (SPS) to select either of the 

mixes. If one of the mixes has a 0% value then selecting that mix will turn off the 

mix. 

To Program the Rudder-to-Aileron Mix 

1. Highlight and select RUDD- A/E in the Function List to obtain the Rudder to 

Aileron/ Elevator display. 

2. Scroll to the desired value (aileron or elevator, right or left, position 0 or 

1) and press the roller to select that value. Rotate the roller to program the 

desired mix value. (Positive and negative values are available to reverse the 

direction of the mix.) 

If you want a mix value to always be active, then program that mix value in 

Pos0 and leave all switches set to Pos0. 

3. To select the desired switch, flight mode switch position or throttle position 

to activate mix value Pos0 and Pos1, highlight the desired switch and 

choose 0 or 1. Pos1 has priority over Pos0. 

TRIM (MeCHANICAL TRIM LeVeR) 

In Normal mode only, a throttle trim is available that allows you to adjust the 

throttle trim. The trim value adjusts the overall trim travel of the throttle only at 

low throttle in the normal mode. This adjustment helps fine-tune the sensitivity 

of the throttle trimmer. To adjust the throttle trim authority, highlight TRIM and 

adjust the value using the roller. You can use the onscreen graph to indicate the 

trim value changes. 

Note: The throttle trim lever is only active when the flight mode switch is in the 

normal position. The throttle trim lever has no effect on flight modes 1, 2, 3, 4 or 

in throttle hold. 


25

HOvERING THROTTLE 

Hovering Throttle increases or decreases the servo output via the trimmer or knob 

for the selected points set for the throttle curve. You can use the hovering throttle 

trimmer/knob to shift the curve upward or downward in order to advance or 

reduce rpm in hover. You can activate the HOV function at each point by selecting 

ON under HOV. 

Note: The Hovering Throttle has no effect on flight mode switch positions 1,2,3,4 

or Hold. 

PITCH CURvE 

The 11X offers up to five (5) separate pitch curves with up to 7 adjustable points 

per curve. This function allows you to customize each pitch curve at any particular 

pitch setting. Once the pitch curves are established, each can be activated in flight 

using the 3-position flight mode switch. If the additional 2 flight modes (numbers 

3 and 4) have been activated in the Device Select portion of the system mode, an 

additional switch will be used to activate these modes. 

The flight mode switch offers three selectable positions: 

• N=Normal 

• 1=Stunt 1 

• 2=Stunt 2 



The N (Normal) position is used as the hover pitch curve. 

Positions 1 and 2 (Stunt 1 and Stunt 2) are typically used for forward flight and 

3D maneuvers. Optional flight modes 3 and 4 are also designed for use with 

aerobatic maneuvers and forward flight. 

Note: The hovering pitch trimmer is only operable when the flight mode switch 

is in the normal position. In the 1, 2, 3, 4 or hold positions, this function has no 

effect. Also, adjusting the hovering pitch trimmer has no effect on the input values 

of the pitch curve. Each of the eight points of the throttle curve are independently 

adjustable from 0–100%. 

EXPONENTIAL 

The Exponential function blends the Pitch Curve between the points on the graph 

to provide a smooth response. The default value is OFF. To turn it on and smooth 

the pitch curve, highlight and select OFF and it will toggle to ON. 

HOvERING PITCH 

Hovering Pitch increases or decreases the servo output via the trimmer or knob 

for the selected points set for the pitch curve. You can use the hovering pitch 

trimmer/knob to shift the curve upward or downward in order to advance or 

reduce Pitch in hover. 

Note: The Hovering Pitch has no effect on flight mode switch positions 1,2, 3,4 

or Hold. 

Accessing the Pitch Curve function 

1. In function mode use the Roller to highlight the Pitch Curve function, then 


access the Pitch curve screen. 

2. Move the flight mode switch to the desired position to select the flight mode 


screen. 

3. Move the Roller and highlight the throttle point you want to adjust. Press 

the Roller to access the point value. Then roll the Roller to increase and 


4. To set pitch curves for flight modes, switch the flight mode to the desired 

position, and the screen will change to that flight mode. 

5. Highlight the desired pitch point you want to adjust and press the roller. 

Rotate the roller to adjust that point on the pitch curve. 

6. To add a point move the throttle stick to the desired position until STOR 

appears on the left bottom of the screen. Press STOR to save a new point at 

that position. 



TAIL CURvE - 

(USe ONLy WITH NON-HeADING HOLD GyROS) 

The 11X offers up to five (5) separate tail curves with up to eight adjustable points 

per curve. This function allows you to optimize the tail curve to counteract torque 

at all pitch positions in every flight mode. Once the tail curves are established, 

you can activate each using the flight mode switch(s). If you activated the 

additional 2 flight modes (numbers 3 and 4) in Device Select, you will use an 

additional switch to activate these modes. Two additional tail curves will be 

available. 

The flight mode switch offers five selectable positions: 

• N=Normal 

• 1=Stunt 1 

• 2=Stunt 2 



Accessing the Tail Curve function 

1. In function mode use the Roller to highlight the Tail Curve function, then 


access the throttle curve screen. 

2 Move the flight mode switch to the desired position to select the flight mode 


screen. 

3 Move the Roller and highlight the desired point you wish to adjust. Press 

the Roller to access the point value. Then roll the Roller to increase and 


4. To set tail curves for flight modes, switch the flight mode to the desired 

position. The screen will change to that flight mode. 

5. Highlight the point you want to adjust and press the roller. Rotate the roller 

to adjust that point on the tail curve. 

6. To add a point, move the throttle stick to the desired position until STOR 

appears on the left bottom of the screen. Press STOR to save a new point at 

that position. 



Exponential 

The Exponential function blends the Curve between the points on the graph to 

provide a smooth response. The default value is OFF. To turn it on and smooth 

the tail curve, highlight and select OFF and it will toggle to ON. You can select an 

Expo function independently for each flight mode. 

Note: Flight Modes ST-3 and ST-4 only show if activated previously in Device 

Select in the System List. 

THROTTLE HOLD 

The Throttle Hold function holds the throttle output position in a specific position 

when the throttle hold switch is activated. But it still allows full pitch and cyclic 

control. Throttle Hold is normally used for autorotations or as a throttle safety 

switch with electric models. 

The Throttle Hold switch defaults to the top right-rear corner of the transmitter. 

However, you can select a different switch in the Device Sel section in System 

Mode. In the forward position, Throttle Hold is on; in the rear position, Throttle 

Hold is off. 

Accessing the Throttle Hold function 

1 Highlight and select Throttle Hold in the Function List to obtain the Throttle 

Hold Display. 

2 Press the Roller to activate (ACT) or inhibit (INH) the Throttle Hold function. 

3. Once the Throttle Hold function is activated, the screen displays the current 

Throttle Hold value. 

4. Move the Roller to highlight HOLD Pos, then press. Roll the Roller to 

increase or decrease the Throttle Hold value to the desired position. 

Note: When Throttle Hold is activated and the switch is on, the “HOLD” 

indication on the main screen displays on the lower right side of the screen. 

STICK AUTO 

The Stick Auto function allows you to activate throttle hold automatically when 

the Throttle Hold switch is activated and throttle reduced below the programmed 

position. Although the Throttle Hold switch is active, with this feature the throttle 

continues to function until you move the throttle stick below the cut position you 

select. 

To Activate the Stick Auto Function 

1. Highlight the Stick Auto function with the roller; press to access. Next, roll 

the roller to increase/decrease the position of the cutoff point. 

HOLD DELAY 

The Hold Delay function allows the throttle servo’s movement to slow when you 

switch from Throttle Hold back to a previous Flight Mode. This feature is helpful 

when practicing Autos. If you abort the autorotation attempt, when the Throttle 

Hold switch is selected to the off position, the throttle increases slowly. This 

eliminates the sudden burst of power and prevents damage to the gear train. The 

Hold Delay adjustable range is from 1/10th of a second up to 2 seconds. 

To Activate the Hold Delay 

1. Highlight the Hold Delay function with the roller; press to access. Next, roll 

the roller to the desired delay position, and press the roller to store. A good 

starting value is .75 (3/4) of a second. 

GYRO SENSOR 

The 11X offers three different types of Gyro Gain Sensitivity Adjustments: manual, 

flight mode or automatic. This feature gives you the choice of selecting gyro 

sensitivity through the rudder, aileron or elevator dual rate switches (manual), 

selecting one of three available gain settings for each flight mode (FOMD) or 

automatically selecting a gain for each flight mode (up to 6 gain settings). You 

can set up the gyro program for normal or tail lock gyros. In tail lock mode the 

value correlates with the actual percentage of the gyro output. A time lag feature 

delays the gain input when switching from tail lock to conventional mode. This 

prevents the tail from jumping when switching modes. It can be toggled on or off. 

Note: To access the gyro function, you must program the Gear, Aux1 or Aux 2 

channels to GYR in device select code 17. You must plug the gyro gain lead into 

this channel. 

Accessing the Gyro Gain function 

1 Use the Roller to highlight Gyro Sens in Function Mode to access the Gyro 

Sensor function. 

2 To select the switch or function you will use, select gyro gain settings. 

Highlight Manual then press the Roller to select the desired switch, auto or 

FMOD. 

3 To select the gyro type, use the Roller to highlight NORM. Next, select 

T.LOCK if you have a tail lock or heading lock gyro or NORMAL for a 

conventional gyro. 

4 Use the Roller to select the gain position to adjust. Press and roll the Roller 

to increase or decrease the gain values as needed. 

5 If you selected AUTO mode, when you have set the gain values for positions 

0, 1 and 2, move the Roller to highlight the mode positions (NORM, ST-1, 

and ST-2). Select the gain position (value) for each mode. 


27

GOvERNOR 

The 11X Governor function is designed to be used with most currently available 

Governors. The function allows you to set rpm values for each of the Active Flight 

modes. The Governor rpm values will automatically change when the Flight Mode 

switch is moved to each of the active flight modes. 

The value range in the Governor function is –125% to 125%. These values follow 

the Travel Adjust values. In other words, a desired Travel Adjust value of +55% 

would also be +55% in the Governor function. You can assign the Governor 

program’s operational channel to the Gear, Aux1 or Aux2 channels in the Device 

Select screen. 

Note: To access the Governor function, you must program the Gear, AUX1 or 

AUX 2 channels to GOV in device select code 17. The governor lead must aslo be 

plugged into this channel. 

Accessing the Governor function 

1 Move the Roller to highlight the Governor function. Press the Roller to 

access. 

2 Highlight the value you want to adjust with the Roller, and then press to 

access the value. Roll the Roller to adjust the value as needed. 

SWASH MIX 

The Swash Mix screen has several important functions. These functions include: 

AILERON, ELEvATOR AND PITCH 

AUTHORITY 

This function independently adjusts the maximum travel of the servos working 

in unison for aileron, elevator and pitch control. If the aileron value is increased, 

the servos that control aileron only (the pitch and aileron servos) increase travel 

when the ailerons are deflected. This will not affect pitch or elevator travel. 

Conversely, if you increase the pitch value, all three servos (aileron, elevator and 

pitch) increase travel when the pitch stick is moved. However, aileron or elevator 

inputs will not be affected by this travel increase. To reverse the direction of travel 

you can select a – (negative) value. The adjustment range is from -125 to +125% 

(defaulted to +60). 

AILERON TO ELEvATOR/ ELEvATOR 

TO AILERON MIX 

This mix corrects swashplate interactions. For example, you can correct elevator 

input that results in slight roll output by mixing elevator to opposite aileron. You 

can select switches or flight modes (SE SEL) to turn this mix on/off. Generally, 

this mix is turned on in stunt modes only. 

3D eLeCTRONIC CyCLIC RING (e-RING) 

When active, the 3D electronic cyclic ring prevents the cyclic servos (aileron, 

elevator and pitch) from overdriving when you give a command of full elevator 

and aileron. This is commonly used for 3D helicopters that are set up to give 

maximum swashplate travel for high cyclic rate maneuvers. 

EXPONENTIAL fUNCTION 

An exponential function is available that compensates for CCPM servo horn nonlinearity 

at the extremes of travel. This function should always be turned on. 

Note: You must select the swashplate type in the Swash Type function in the 

System List. 

Accessing the Swashplate Mixing function 

1 Use the Roller to highlight the Swash Mix function in Function List. 

2 To select the aileron, elevator or pitch authority, highlight the value next to 

the desired channel and press the roller to select the value. Rotate the roller 

to adjust the value. 

3 To program an Aileron-to-Elevator or Elevator-to-Aileron mix, highlight the 

value below the desired mix. Press the roller to select the value. Note that 

right and left values are available. Rotate the roller to adjust the value. 

4 To select a switch, turn on/off the aileron/elevator and elevator/aileron mix, 

then highlight SW SEL. A screen appears that allows you to select several 

switches and flight modes to turn on/off the mix function. 

5 To activate the 3D cyclic ring, highlight INH next to E-RING. Toggle the roller 

to ACT. 

6 To activate the exponential function, highlight OFF next to EXP. Toggle the 

roller to ON. 

TRIM SYSTEM 

The Trim System function adjusts the sensitivity of the 11X trim levers and the 

Flap and Aux trimmers. The standard digital trims are adjustable from 0–10 with 

10 being the coarsest adjustment and 0 being trim off. Adjusting the digital trim 

values has no effect on the total trim travel, however, it affects the resolution of 

each trim input. When the value is set to 10, each click of trim adjusts the servo 

output by 10ms and there are only 10 trim increments from center to each end. 

When set to 5, the output is changed 5ms per trim step and there are 20 trim 

increments from center to each end. When set to 1, each click of trim changes the 

servo output by 1ms and there are 100 trim increments. When set to 0 the trim 

levers cease to function effectively, turning off the trim function. The Flap and Aux 

Trimmers are adjustable from 0 to 200 and can be turned on/off. When adjusted 

to above 100% the trimmer functions as a two- or three- position switch. 

Reducing the value increases the number of output positions. 

The trimmers can also be set to function as a momentary switch by selecting 

ON under Moment for either or both trimmers. When adjusting the digital trims 

(AILE, ELEV, RUDD), the total trim travel does not change – only the number of 

increments (beeps) changes, which makes for finer or coarser trim movements. 

When adjusting the analog throttle trim, however, the total trim travel is actually 

reduced when set to less than 100%. Use a fairly coarse setting, such as the 

factory default 4, when test flying a model for the first flights in order to be able to 

trim it quickly; use a finer setting, such as 3–1, for final precision trimming. 

L.S.T. TRIM (LIMITeD STANDARD TRIM) 

The L.S.T. trim feature has two options: L.S.T. and normal. In normal, when 

making trim changes using the aileron, elevator or rudder digital trims, the center 

as well as the endpoints is affected by the trim values. The right trim causes 

the center, the right endpoint and the left endpoint to all shift to the right. When 

L.S.T. is activated, only the center position is trimmed. The center is shifted to the 

right but the endpoints are not affected. This is useful for aircraft that have a hard 

stop endpoint to prevent over-travel caused by trim or if it’s desired to have trim 

changes not affect the total roll pitch or yaw rate. 

To Adjust the Trim Rates 

1 Highlight and select Trim System in the Function List to acquire the Trim 

System function. 

2 Highlight and select the trim that is to be changed and use the Roller to set a 

value of 1–10 (1 = finest, 10 = coarsest). 

Note: The Flap and AUX trims are adjustable from 0 to 200 and can be 

turned off or on by selecting On or Off. 

3 Repeat for other trims as desired. 

To Select the L.S.T. Trim function 

1 Highlight and select the L.S.T. or NORM setting next to the desired channel 

(AILE, ELEV or RUDD) and press the roller to select L.S.T. or NORM. 

2 Repeat for other channels as desired. 

SLIDE CAMbER 

The Slide Camber function adjusts the up and down flap travel when using the 

Flap Lever (default) or whichever switch you selected to operate the flaps in 

Device Select. Each flight mode activated in Device Select will display with an 

up and down value in the Slide Camber screen. The adjustment range is +125% 

to-125%. Use Slide Camber in conjunction with the Flaperon Mix function to 

adjust the desired camber setting ranges, when using the flap levers for each 

flight mode. 

To Access the Slide Camber Function 

1 Highlight and select Slide Camber in the Function List. 

Note: Flap values are available for each active flight mode, and you can 

independently adjust the values up and down. 

2 Rotate the roller to highlight the value next to the flight mode. Press the 

Roller to access the Slide Camber for the intended flight mode and press the 

roller. 

3 Rotate the roller to adjust the value. 

4 Repeat for all positions and flight modes as desired. 

MOTOR SYSTEM 

Note: This function is only available when the motor is programmed to the 

spoiler stick in the Device Select menu. 

The Motor System feature allows the spoiler stick to be used for multiple 

functions. In one mode (Launch Mode, for example) you can use it as a 

proportional throttle for an electric motor. Switching to another mode (Float), you 

can use the spoiler stick as landing flaps. When the Motor System mix is on, the 

Motor System program holds the throttle in the desired position, usually motor off. 

To Access Motor System 

1 Rotate the Roller until Moto System is highlighted. Press the Roller to 

access the Motor System menu. 

2 Rotate the Roller to highlight desired flight mode or switch, then press the 

Roller to access on or off. 

3 Adjust the motor value to achieve the desired throttle position for that flight 

mode or switch. 

Note: The AND function requires all selected switches to be On in order to 

activate the Motor System function. If AND is left Off, only one of the 

selected switches need be On to activate the Motor System function. 

4 A delay can be added when the motor is throttling up and when throttling 

down. Both delays are adjustable from 0 to 2 seconds. To add a delay on 

throttling up, highlight and select INH next to the up arrow, and adjust the 

value as desired. To add a delay on throttling down, highlight and select INH 

next to the down arrow. Adjust as desired. 

CAMbER PRESET 

The Camber Preset system allows preset camber adjustments for each 

programmed flight mode for the right and left ailerons, the right and left flaps, and 

if activated the right and left tip ailerons. It also allows you to adjust the preset 

camber setting that is automatically selected with each flight mode. 

The available Delay function causes the smooth transition of the control surfaces 

from one flight mode to the next. Plus, a Break function is available that reduces 

the camber at a preset elevator stick position. Flap and Flaperon trim steps are 

also adjustable in the Camber Preset system. 

The Camber Preset system combines four mixes in one screen. Mixes include 

Flap- to-Flaperon mix, Flap-to-Elevator mix, Aileron-to-Flap mix, and Aileron-to- 

Tip aileron mix, if the tip ailerons are activated in the wing type function. 

The flap lever-offset position is programmable allowing pilots to choose the 

neutral position. You can program the flap functions to one of many different 


29

levers or switches in the Device Select screen. The default is the left lever. Mix 

values are based on a percentage of the flap values, so until you program a flap 

value in the Slide Camber function, the Flaperon Mix function will not operate. 

To Access the Camber Preset system 

1 In the Function List rotate the Roller until Camb Preset is highlighted. Press 

the Roller to access the Camber Preset menu. 

2 If you wish to program a Break point with elevator input (reduces camber 

with elevator input), highlight Elevator STK and program the desired Elevator 

offset. This value establishes the point at which the reduction of camber 

occurs. 

3 Rotate the Roller to highlight the desired value then press the Roller to 

access this value. With the flight mode switch in the corresponding mode, 

adjust the value to the desired position for each control surface. Repeat this 

for all desired flight modes and control surface positions. 

4 If desired, you can program a delay that smoothly transitions the control 

positions when changing from one flight mode to the next. The adjust range 

is from INH to 6.0 seconds or hold. 

LANDING MODE 

The Landing Mode mixes the spoilers, flaperons, flaps, and tip ailerons (if 

equipped) and elevator to the spoiler (throttle) stick. Two values are available, 

Pos0 and Pos1. You can assign each to several different switches or flight modes. 

The provided offset (Brake Start POS) allows the user’s preference for the neutral 

position (normally stick up). 

To Access the Landing Mode 

1 In the Function List rotate the Selector until Landing Mode is highlighted. 

Press the Selector to access the Landing Mode function. 

Note: The default setting for Brake Start POS offset position is at +95%. 

With this setting, the flap’s neutral position (trailing edge level) occurs when 

the spoiler stick is in nearly the full up position. If you choose to locate the 

neutral position in the down position, the value would be –100%. 

2 Rotate the Selector to highlight SW SEL. Press the Selector to access the 

available switches. Select a switch and switch position if desired. Highlight 

and select SW SEL to exit the switch selection list. 

3 To access the various values, rotate the Selector to highlight them. Press the 

roller to access the value. Move the spoiler stick to the full down position 

and adjust the value by rotating the Selector until the desired position is 

achieved. Press the Selector to store the value. 

4 Rotate the roller to access the Landing Flaperon and Elevator mixes. These 

allow you to store and program up to 7 points. This system also allows up 

to 7 points on a curve to be adjusted for Flap-to-Elevator mixing and Flapto-Flaperon 

Mixing. 

5 Move the spoiler stick up and down until you see ADD on the lower left 

corner of the screen. When in the stick position desired, press ADD to add 

an additional point to the curve mix. 

6 Adjust each mix value as desired. 

7 Press the LIST button to return to the Function Mode screen. 

DIffERENTIAL 

The 11X Differential function reduces the travel of the Aileron that deflects 

downward without affecting the Aileron that travels upward and, therefore, can 

eliminate adverse yaw tendencies in rolling maneuvers. Differential is also 

available for the Rudder and Flap channels if Dual Rudder and/or Dual Flap is 

selected in the Wing Type menu. 

The Aileron Differential function provides independent differentials for each flight 

mode. A Break feature adjusts the point at which the differential begins based on 

the Spoiler Stick. 

To Use the Differential function 

1 Highlight and select Differential in the Function List to obtain the Differential 

display. 

2 Select the desired Flight Mode and set the Aileron differential as desired. A 

positive value causes the downward Aileron to travel less while a negative 

value causes the upward Aileron to travel less (negative differential). 

3 If you want to use a Break to activate the Differential based on Spoiler Stick 

position, select the Break value for each Flight Mode and adjust as desired. 

Adjust the value so the differential begins where desired on the Spoiler 

Stick. 

4 Repeat steps 1 and 2 for the Rudder and Flap channels if activated. Dual 

Rudder and Dual Flap must be selected in the Wing Type menu for Rudder 

and Flap Differential to be available. 

fLAPERON MIX 

Flaperon Mix Combines four mixes in one screen. Mixes include Flap-to- 

Flaperon mix, Flap-to-Elevator mix, Aileron-to-Flap mix, and Aileron-to-Tip 

aileron mix, if the tip ailerons are activated in the wing type function. The flap 

lever-offset position is programmable allowing you to choose the neutral position. 

You can program the flap functions to one of many different levers or switches in 

the Device Select screen. The default is the left lever. 

Mix values are based on a percentage of the flap values, so until you program a 

flap value in the Flap Rate function, the Flaperon Mix function will not operate. 

To Access flaperon Mix 

1. In the Function List, rotate the Roller until Flaperon Mix is highlighted. 

Press the Roller to access the Flaperon Mix menu. 

2 Highlight Flap LV Offset and program the desired Flap lever offset. This 

value establishes the center point at which the up/down or left/right mix 

occurs. 0 is center position. 

Note: The flap defaults to the left lever but can be changed in Device Select. 

3 Rotate the Roller to highlight the desired value then press to access. With 

the flight mode switch in the corresponding mode, move the programmed 

flap lever to the appropriate position and adjust the value to the desired flap 

position. Repeat this for all desired flight modes and flap positions. 

4 Press the LIST button to return to the Function Mode screen. 

AILERON-TO-RUDDER MIX 

Aileron-to-Rudder mix causes the rudder to move in unison with the ailerons. You 

can use it to reduce adverse yaw and improve turning/handling characteristics. 

You can independently adjust Aileron-to-Rudder mix values right and left for each 

of the 5 flight modes. 

To Access Aileron-to-Rudder Mix 

1 In the Function List rotate the Roller until AIL-RUD is highlighted. Press the 

Roller to access the Aileron-to-Rudder mix menu. 

2 Rotate the Roller to highlight the desired value corresponding to the flight 

mode and desired direction. Press the Roller to access that value. With the 

flight mode switch in the corresponding mode, give an aileron command 

and rotate the Roller to achieve the desired rudder value. Press the Roller to 

store the value. 

3 You can program Elevator and rudder break points. They reduce the aileronto-rudder 

mix when the elevator or rudder stick is displaced. 

SNAP-fLAP MIX 

The Snap-Flap mix gives several degrees of down flap when up elevator is 

applied. This gives more pitch authority than would elevator alone. Snap-Flap 

mix values are available for each active flight mode and can be independently 

adjusted up and down. 

An offset is available that allows the programming of snap-flaps. With snap-flaps, 

there is no flap mixing during small-to-medium up-elevator inputs. However, at 

the offset point of up-elevator, the flaps are mixed to give down flaps, causing 

greater up-pitch authority 

flight Tip: Snap-Flap is commonly used by slope racers to improve high-speed 

turns. In thermal sailplanes, it allows increased maneuverability for tight thermal 

turns. 

To Access Snap-flap Mix 

1 In the Function Mode list, rotate the Roller until Snap-Flap is highlighted. 

Press the Roller to access the Snap-Flap mix menu. 

2 If you choose to program snap-flaps, the offset adjustment range is -200 to 

+200. Negative values move the offset in the up-elevator direction. 

Switches are available at the bottom of the screen that allow the selection of 

Pos0 or Pos1. 

RUDDER-TO-SPOILER MIX 

The Rudder-to-Spoiler mix causes the spoiler to move in unison with rudder. You 

can independently adjust Rudder-to-Spoiler mix values for each of the 5 flight 

modes. 

Note: Dual spoilers must be activated in Wing Type in order to access the 

Rudder-Spoiler mix. 

flight Tip: You can use this mix to improve turning/handling characteristics, 

especially on landings. 

To Access Rudder-to-Spoiler Mix 

1 In the Function List rotate the Roller until RUDD-SPOI is highlighted. Press 

the Roller to access the Rudder-to-Spoiler mix menu. 

2 Rotate the Roller to highlight the desired value corresponding to the flight 

mode. Press the Roller to access that value. With the flight mode switch in 

the corresponding mode, give a rudder command and rotate the Roller to 

achieve the desired spoiler mix value. Press the Roller to store the value. 

INTRODUCTION TO MIXERS 

The 11X provides 3 Standard programmable mixes (PROG. MIX1 - PROG.MIX3) 

and 3 Multi-Point or Curve programmable mixes (PROG.MIX4 - PROG.MIX6). 

Programmable mixers are programmed to cause a second channel to react to 

input to the primary channel or to cause a channel to be controlled by moving 

a switch or lever. The primary channel is called the Master channel, while the 

channel that reacts to the Master is called the Slave channel. 

Programmable mixes are typically used to activate special aircraft functions like 

smoke systems, speed brakes, steerable nose gear, bomb drops, idle-up, etc. or 

to alter flight characteristics. For example you can program down elevator at low 

throttle for aerobatic aircraft such that the aircraft tracks perfectly on the down 

lines at low throttle. 

Multi-Point (or Curve) Mixing provides the ability to program a customized curve 

that the Slave channel follows as it reacts to the Master channel’s input. Multi 

Point mixes are different from Normal Mixes in that Normal Mixing results in a 

restricted movement of the Slave channel in relation to the Master. With Multi- 

Point Mixing you can adjust up to 7 points to control the position of the Slave 

channel, providing the ability to custom tailor the output of that channel. 

Mixes are fully programmable, allowing any of the 11 channels to be Master, 

Slave or both (a channel can be mixed to itself). You can also use trimmers and 

levers as a master and for programming a proportional channel to be operated via 

a trimmer or lever. Additionally programmable mixes can always be on, or turned 

off and on via a programmed switch, Stick position or flight mode. The Snap Roll/ 


31

Trainer, switch (momentary switch SNPT) can also be programmed as the Master 

channel. 

If you activate dual functions in the Device Select screen, the following slave 

channels are available: AILV, FPRN, FROL, and RUDV. These functions allow 

the ailerons to be moved as flaps, flaps to be moved as ailerons, elevators to be 

moved as ailerons, rudders to be moved as speed brakes, both in or both out. 

There are 2 options for Master channels: 

“#” (pound sign). These Master channels are Origin-type mixes. Origin 

mixing bypasses any other mixing affecting that channel, such as throttle curves, 

exponential or travel adjust, and uses the stick position only to control the mix. 

“+” sign. These Master channels are include-type mixes. Trim Include mixes 

include the trim of the Master channel and any other mixing to the Master channel 

if selected to control the Slave channel of the mix. 

fUNCTIONS Of THE STANDARD 

PROGRAMMAbLE MIXER 

Standard Programmable Mixer - (Std. Prog Mixer) 

The 11X has 3 standard programmable mixers that allow linear mixing of a 

Master channel to a Slave channel. The standard mixers are PROG.Mix 1, Mix 2, 

and Mix 3. 

These mixes provide two sets of mixing values named Pos0 and Pos1. If one set 

of values is set to 0%, you can turn the mixer On and Off with a stick, switch, or 

lever. Each set of mixing values has 2 percentages to accommodate movement of 

the Master channel in both directions. This is shown in the illustration below with 

an upper and lower percentage for both Pos0 and Pos1. 

You can set a mix to always be on by setting Pos0 values only and not selecting 

any switches to switch between the Pos0 and Pos1 values. 

MASTER CHANNEL - (STD. PROG MIXeR) 

The Master channel is the primary or controlling channel. The default for both the 

Master the Slave channel is THRO. Highlight and select the Master parameter to 

obtain a list of channels. Select the Master channel from the list. 

If the master channel selected is capable of include or origin mixing, a pop-up 

menu will appear with a list of include functions available. Generally, you can 

include the Trim, so the trim for the master channel also functions on the slave 

channel. Additionally, you can set D/R & EXP settings and some mix functions to 

include, so they function on the slave channel as well. 

If all include settings are set to OFF, then the mix is an Origin-type mix. In such 

a mix only the master channel control stick or switch functions on the slave 

channel. 

SLAvE CHANNEL - (STD. PROG MIXeR) 

The Slave channel is the secondary receiving channel and moves according to the 

program mix in relation to the Master channel. The default for both the Master the 

Slave channel is THRO. 

Highlight and select the Slave parameter to obtain a list of channels. Then select 

the Slave channel from the list. The list contains each of the 11 channels in the 

system and CANCEL. 

SWITCH POSITION 

The left side of the Programmable mix screen displays the available switch 

options. If you want a switch to control the mix, either on/off or have two mix 

values, highlight and select the desired switch(s) and select position 0 or 1. Each 

standard programmable mixer has two positions - Pos0 and Pos1 and each 

position has 2 percentages (upper and lower) to accommodate mixing when the 

Master is moved in both directions. Note that Pos1 has priority over Pos0. 

OffSET 

Offset defines the position where the mixer changes direction. The Offset defaults 

to center position or 0 and is most commonly used. With a 0 Offset, if the Rudder 

is Master, moving the rudder stick to the left of center causes a mix in one 

direction while moving the rudder stick of the right of center causes a mix in the 

other direction. Directions correspond to the upper and lower percentages for 

Pos0 and the upper and lower percentages of Pos1. The amount of mix and actual 

direction the slave moves is determined by the Pos0/Pos1 values. Offset applies 

to both Pos0 and Pos1 settings. 

To change Offset, highlight and select Offset and adjust with a positive (+) or 

negative (-) value. A positive percentage moves the offset in one direction from 

center while a negative percentage moves it in the other direction from center. 

MIX vALUES 

Pos0 settings determine how far, and in which direction, the slave channel moves 

when the master is moved above and below the Offset and the switch is in a 

position to select the Pos0 values. 

To enter Pos0 values, highlight and select Pos0. Move the Master channel control 

(stick, lever or switch) in one direction and set the percentage. Then move the 

Master channel control in the other direction and set its value. 

Pos1 settings are identical to the Pos0 settings. They determine how far, and in 

which direction, the slave channel moves when the master is moved above and 

below the offset and the switch is in a position to select Pos1 values. 

To enter Pos1 values, highlight and select Pos1, move the Master channel control 

(stick, lever or switch) in one direction and set the percentage. Then move the 

Master channel control in the other direction and set its value. 

CLR bUTTON - (STD. PROG MIXeR) 

SLAvE CHANNEL 

Pressing the CLR button with a modifiable mix selected resets the parameter to 

its default value. Pressing the CLR button when the Master or Slave channel is 

highlighted Inhibits the entire mix, making it no longer functional. 

TO INHIbIT A MIX 

Highlight either the Master or Slave and press the CLR button to completely 

disable a mixer. 

MULTI-POINT PROGRAMMAbLE 

MIXER 

There are 3 Multi-Point Programmable Mixers in the 11X - Prog. Mix4 through 

Prog.Mix6. They differ from standard mixes because they allow non-linear mix 

response from the Master to the Slave. They use up to 7 points to define the 

position of the slave channel in relation to the Master channel at up to eight 

selectable points. As the Master reaches each point, the Slave response position 

can be defined independent of other point settings. 

POINT NAMES/NUMbERS 

The adjustable points list vertically by name and display by number along the 

bottom of the graph. 

To change the value of a point, highlight and select the point name then dial in the 

desired percentage. 

CURRENT POINT SETTING 

This list shows the setting for each of the 7 adjustable points (Point-L, 1, 2, 3, 4, 

5, H). The value of each point determines where the point is positioned vertically 

on the graph, dictating the Slave servo position relative to the Master. You can 

set the point values from -100 to +100. A value of 0 indicates the Slave’s center 

or neutral position. The overall travel of the slave channel is affected by the Travel 

settings described in the TRVL ADJ. function. 

To change the value for a point, highlight and select the Point Name to the left of 

the point value. Then dial in the desired value. 

Pressing the CLR button when a point value is highlighted resets the point to 

original settings. 

vERTICAL LINE 

The Vertical line on the graph shows the current Master channel position. When 

you deflect the Master channel fully in one direction, the line is to the extreme 

left over Point-L. At neutral, the Master channel is in the center over Point-1. 

When fully deflected in the other direction, the cursor is at the extreme right of 

the graph over Point-H. Where the vertical line intersects, the Curve/Line over a 

given point defines the Slave servo position, which is equal to the value assigned 

to that point. 


33 

GRAPH 

The graph illustrates the mixing curve. The X-axis (horizontal plane) represents 

Master channel movement. The Y-axis (vertical plane) represents the Slave servo 

movement. The bottom half of the graph is one direction from neutral, and the top 

portion of the graph is the other direction. 

POINTS YOU CAN ADD AND ADJUST 

Curve mixes default to three points (L, 1 and H). You can add up to four 

additional points. To add a point, move the master channel in the desired position 

until STOR appears on the left bottom of the screen. Press STOR to save a new 

point at that position. 

To eliminate a point, press ERASE (bottom left of the screen) when the point is 

highlighted by moving the master channel. 

EXPONENTIAL 

The Exponential function blends the Curve between the points on the graph to 

provide a smooth response. The default value is OFF. To turn it on and smooth the 

mixing curve, highlight and select OFF. It will toggle to ON.

SLAvE CHANNEL POSITION 

The Slave servo position next to OUT at the bottom left of the screen displays 

in values from -100 to +100. 0 is neutral or center. This position represents the 

servo travel that corresponds to the present Master channel position. 

MASTER CHANNEL POSITION 

The Master channel position displays on the bottom line of the screen next to 

IN. It is expressed in values from 0 to 100. 50 is center or neutral. This position 

represents the present Master channel position. 

MIX TO THROTTLE 

The 11X Cyclic-to-Throttle function adds throttle to prevent main rotor rpm decay 

that results from load changes placed upon the engine when Aileron, Elevator or 

Rudder is given. The most common use for Cyclic-to-Throttle mixing is for Stunt 

Modes. This allows the main rotor rpm to remain consistent throughout aerobatic 

and 3D maneuvers. Normally, Cyclic-control to-Throttle mixing is not used in 

Hover (Normal) mode since control inputs are generally small and much less 

aggressive. 

Note: If you are using a Governor for rpm control, it is not necessary to use the 

Cyclic-to-Throttle Mixing. Further, all values should be left at the factory default 

position (0%). 

Programming the Cyclic-to-Throttle function 

1 In Function mode highlight the Mix-Thro function. Press the Roller to 

access the Mix-Thro screen. 

2 Highlight the value you want to adjust, then press to open the options box. 

Roll the Roller to adjust the value as needed. 

SELECTING THE DESIRED fLIGHT 

MODES fOR CYCLIC-TO-THROTTLE 

MIXING 

The 11X allows you to select the specific flight modes in which the Cyclic-to- 

Throttle mixing will be active. The factory default position is ON for all flight 

modes, which is not recommended in most cases. The Cyclic-to-Throttle mix is 

generally used for Stunt (flight) modes only, so it will be necessary to select the 

Cyclic-to-Throttle mixing for the desired flight modes. 

1 Move the Roller to highlight the SW SEL for each of the Cyclic-to-Throttle 

mixes to be used. 

2 Press the Roller to open the Flight Mode options box. Highlight the desired 

flight mode to be set (NRM, ST1, ST2, ST3, ST4, GEAR). Press the Roller to 

turn the mixing on or off for each of the active flight modes. 

f-MODE DELAY 

You can use the Flight Mode Delay function to delay the transition from a stunt 

mode to normal flight mode. The delay function slows the selected channel’s 

changes that are caused by switching from a stunt mode to normal flight mode. 

Some of those changes include throttle curves, pitch curves, Dual Rates, etc. 

This is useful for transitioning from a stunt mode with a V-pitch curve to normal 

mode with a linear curve to slow the transition and prevent the helicopter from 

jumping quickly. 

To Program a f-Mode Delay 

1 Highlight and select F-Mode Delay using the Roller in the Function List. 

2 Highlight and select INH next to the desired channel to apply a delay. 

3 Rotate the roller to adjust the setting from INH to 6.0 seconds. 

GYRO GAIN SYSTEM [SeNSOR] 

The Gyro Gain system allows in-flight selection of up to 3 gyro gain settings 

for up to two separate gyros, or up to three gyro gain settings assigned to flight 

modes. The system provides for fixed gain values and has settings for normal or 

tail lock gyros. You can assign and select Gyro gains via a three-position switch 

or with Flight Modes. 

If one set of gains for a gyro is set to 0% in normal gain mode, you can switch the 

gyro off during flight. 

GYRO CONNECTIONS 

Plug the gain connector of one gyro into the AUX2 port of the receiver. Plug the 

gain connector of another gyro (if used) into the AUX3 of the receiver. If using 

only one gyro, connect its gain to either AUX2 or AUX3. 

GYRO SENSOR [GAIN] 

In order for the Gyro Sens to appear in the Function List, you must program the 

Device Select function to GYRO on the GEAR, FLAP, AUX2 and/or AUX3 channels 

to be active. 

Use this function only with gyros that have in-flight proportional gain adjustment 

capability. Single and dual rate gyros that use a potentiometer to adjust the gain 

will not work with this function. 

To Access the Gyro Sensor 

1 Highlight and select Gyro Sens. in the Function List. 

2 Highlight MANUAL then decide which switch to use to control gyro gain. 

Highlight and select AILE D/R, ELEV D/R, FLAP SW, AUX2 or AUTO (for 

flight mode). 

3 Two types of gyro adjustments are provided, Normal and Tail Lock. Highlight 

and select the desired type of gyro. If selecting heading lock, note that a T 

or N is available for each gain setting. If T is selected, the gyro will be in tail 

lock mode. If N is selected, all values for that gain will be in normal mode. 

For most airplane applications normal mode is recommended. 

Note: Time Lag is available in Tail Lock mode when switching from tail lock 

to normal mode. This prevents the servo attached to the gyro from jumping 

abruptly when switching from tail lock to normal mode. 

4 Each gyro has 3 available gain settings. They are labeled Pos0, Pos1, and 

Pos2 with a percentage next to each. They correspond to the positions of 

a 3-position switch. 0 represents the switch being in the upper position; 1 

represents the middle position; and 2 represents the lower position. 

5 Use the Roller to highlight and select the number 0 position for each gyro 

and set the percentage to the desired gain value. 

6 Select the number 1 gain for each gyro and set it to the desired value. 

7 Select the remaining gain values. 

TRIM SYSTEM 

The Trim System function adjusts the sensitivity of the 11X trim levers. The 

standard digital trims are adjustable from 0–10 with 10 being the coarsest 

adjustment and 0 being trim off. Adjusting the digital trim values has no effect on 

the total trim travel, but affects the resolution of each trim input. When the value is 

set to 10, each click of trim adjusts the servo output by 10ms and there are only 

10 trim increments from center to each end. When set to 5, the output is changed 

5ms per trim step and there are 20 trim increments from center to each end. 

When set to 1, each click of trim changes the servo output by 1ms and there are 

100 trim increments. When set to 0 the trim levers cease to function effectively, 

turning off the trim function. 

When adjusting the analog throttle trim, however, the total trim travel is actually 

reduced when set to less than 100%. Use a fairly coarse setting, such as the 

factory default 4, when test flying a model for the first flights in order to be able to 

trim it quickly. Use a finer setting, such as 3–1, for final precision trimming. 

Also in the Trim system function if flight modes are active, you can select the 

flight mode trims to be common, the same set of trims in every flight mode, or 

select FMOD to have a different set of trims for each flight mode. You can set the 

Flap trim to on or off in the Trim System function as well. Finally, you can leave 

the Flap and AUX levers at the default setting as well as CROSS, which swaps the 

functions of the 2 levers. 

L.S.T. TRIM (LIMITeD STANDARD TRIM) 

The L.S.T. trim feature has two options: L.S.T. and normal. In normal, when 

making trim changes using the aileron, elevator or rudder digital trims, the 

center and endpoints are affected by the trim values. The right trim causes the 

center, right endpoint and left endpoint to all shift to the right. When L.S.T. is 

activated, only the center position is trimmed. The center is shifted to the right 

but the endpoints are not affected. This is useful for aircraft that have a hard 

stop endpoint to prevent over-travel caused by trim or if it’s desired to have trim 

changes not affect the total roll pitch or yaw rate. 

To Adjust the Trim Rates 

1 Highlight and select Trim System in the Function List to acquire the Trim 

System function. 

2 Highlight and select the trim you want to change. Use the roller to set a 

value of 1–10 (1 = finest, 10 = coarsest). 

3 Repeat for other trims as desired. 

To Select the L.S.T. Trim function 

1. Highlight and select the L.S.T. or NORM setting next to the desired channel 

(AILE, ELEV or RUDD). Press the roller to select L.S.T. or NORM. 

2. Repeat for other channels as desired. 

THROTTLE HOLD 

The throttle hold function acts as a kill switch for glow-powered airplanes 

and a safety/arming switch for electric-powered aircraft. You can also preset a 

programmed throttle position for electric sailplanes to give full power when the 

switch is activated. The throttle hold function switch position and direction is 

assigned in Device Select. The programming of the throttle hold switch position 

is done in the Device Select screen in System Mode. 

Note: Throttle Hold defaults to the mix switch. 

To Activate Throttle Hold 

1 Highlight and select Thro Hold in the Function List to obtain the Throttle 

Hold Display. 

2 Highlight IHN and press the roller to activate the Throttle Hold function. 

3 Highlight the HOLD Pos. and press the roller to allow throttle hold positions 

to be adjusted (0% = low throttle low trim. 100% =full throttle). 

Note: The currently selected Throttle Hold switch displayed under ACT. MIX 

SW is the default setting. To select another switch see Device Select Throttle 

Hold on page 14. 

THROTTLE TRIM 

The Throttle Trim function allows a throttle cut feature that cuts the throttle to 

an adjustable setting to kill the engine on a selected switch. An idle adjustment 

feature is also available allowing 2 selectable idle positions through a switch. 

To Program the Throttle Cut function 

1 Highlight and select INH under THRO CUT. 

2 Highlight and select the percentage next to THRO to adjust the position the 

throttle moves to when the function is activated by a switch. Adjust this 

position as necessary so the engine stops running, but does not bind the 

throttle linkage. 

3 You can add a Time Lag to delay the throttle cut function. Highlight and 

select INH next to Time Lag and rotate the roller to select the desired Time 

Lag. The value ranges from INH to 2.0 seconds. 


35

4 Highlight and select SW SEL to select a switch to assign the throttle cut 

function to. 

5 Rotate the roller to select the switch and switch position desired. Press to 

select. 

6 Highlight SW SEL to exit the switch selection menu. 

To Program the Idle Adjust function 

1 Highlight and select SW SEL under IDLE ADJUST on the screen. 

2 Rotate the roller to select the switch and switch position desired. Press to 

select. 

3 Highlight SW SEL to exit the switch selection menu. 

4 Highlight and select +0 under the Idle Adjust and rotate the roller to adjust 

the idle position as desired. 

bALANCE 

The Balance function allows you to adjust the servo outputs of dual channels. 

This is useful when two servos are used to drive a single surface (e.g., two aileron 

servos used to drive one aileron) and the linkage geometry of each servo is 

slightly different (typical with a tapered aileron). 

If you mix both servos in a linear fashion, binding occurs throughout the control 

range due to linkage geometry inaccuracies. The Balance function allows you 

to adjust the servo output of the master servo at 5 points throughout the range, 

compensating for any linkage geometry inaccuracies. Think of Balance as a curve 

mix that allows you to independently adjust the master channels at seven different 

points. This allows a perfect bind-free setup throughout the control stroke. 

To Program the balance function 

Note: Balance is available in the Function List only if Flaperon, Delta or 

4-Aileron is selected in the Wing Type or if any of the dual functions (e.g., dual 

elevator, dual rudder, etc.) are activated in Wing Type. 

1 Highlight and select Balance in the Function List. 

2 Highlight and select the channel you wish to adjust on the left side of the 

screen. 

3 The Balance screen displays functions that are programmed in the Wing 

Type. If Flaperon only is programmed, only one aileron channel appears in 

the balance screen. If 4-Ailerons are selected, then three aileron channels 

appear in the balance screen. This also applies to the dual elevator and 

rudder functions. 

4 Using the roller, highlight the desired position and press the roller to access 

the value. Rotate the roller to change the selected output position. The 

range is +50 to -50. Repeat this for all positions until no binding occurs 

throughout control travel or the left versus right travel is matched. Point P-2 

adjusts that channel’s neutral point, points P-1 and P-3 adjust that channel’s 

100% travel adjust point, points P-L and P-H adjust the selected channel’s 

150% travel adjust point. 

5 If Expo is desired, highlight OFF under EXP and press the roller to select 

ON. Expo will apply a curve response between the points selected. 

STICK POSITION SWITCH 

The Stick Position Switch function allows the throttle, aileron elevator or rudder 

stick positions to turn on/off mixes, change throttle curves, change differential 

rates, start a timer and other functions. An example of this would be a smoke 

system that turns off below 25% throttle to prevent low throttle flameouts. Two 

stick position programs are available and you can assign one or more to various 

mixes or functions. The stick position that turns the Stick Position switch off / 

on is selectable as well as the direction to turn on/off. Also, a symmetrical option 

is available that allows the function to be turned on with a preprogrammed equal 

right or left (up or down) stick position. 

To Program a Stick Position Switch 

1 Highlight and select Stick POS SW using the Roller in the Function List. 

2 Highlight the desired Stick position switch (SPS0 or SPS1) and press the 

roller. 

3 Select the desired channel to trigger the Stick position (Throttle, Aileron, 

Elevator, and Rudder). 

4 Rotate the roller to select POS and adjust to the value you wish to have the 

mix function turn off/on (0 = center, L100= Left full stick travel, etc). ON/OFF 

displays at the top of the screen and when moving the stick, it indicates the 

function is working. 

5 Use the roller to select ON and select Low/ High or Right/Left to access the 

desired direction the function will turn on/off. 

6 The available symmetrical function allows you to turn the stick position 

on/off by moving the stick in either direction. You must first program a 

value in the POS, then highlight the SYM and activate it using the roller. 

You can now program the center to turn on or off by selecting the ON and 

highlighting Low/High or Right/Left. 

TIMER 

The 11X features a sophisticated Timer System with four timers. An integrated 

timer keeps track of total transmitter-on time for the current selected model. 

Integrated time displays on the Main screen. You can set three other timers as 

Countdown timers or as Stopwatches. These timers also appear on the Main 

display when active and can be started and stopped via various switches. 

In addition you can program an interval function so the alarm sounds at 

preprogrammed intervals. You can program a Down Alarm that sounds prior and 

up-to the programmed countdown time. A one-time function sounds the alarm 

once, or continuously, when the time is reached. 

1 To configure the timers, highlight and select Timer in the Function List to 

obtain the Timer display. 

2 Highlight and select INH under TIMER1, TIMER2 or TIMER3 then select 

DOWN-T of STOP W. Use the Roller to set the countdown set time, interval, 

down alarm and one-time functions. Once the timer is set, TIM appears 

on the Main display in the lower left corner. You can program the timers 

to several different buttons or switches. Use the Roller to highlight the 

desired button or switch to operate the timer. Press the Roller to confirm 

the selection. The desired set time, beep interval, down alarm can be set as 

desired. When the One-Time function is ON, the timer starts with the switch 

selected; pressing the switch again will have no effect. If the One-Time 

function is OFF, you can stop and restart the timer as many times as desired 

with the switch selected. 

3 To Reset the Integrated Timer, highlight and select the time under INTEG-T 

and Push [CLR]=0:00 appears on the display. Press the CLR button to the 

left of the display to reset the integrated timer. 

Note: To reset the stopwatch or countdown timer, use the roller to highlight 

the Timer on the main display screen, then press the CLR button. 

MIX MONITOR 

The Mix Monitor screen displays all the mixes, dual channels, wing types and 

snap roll functions. This screen is a convenient way to determine which functions 

are activated. 

1 To access the Mix Monitor screen, highlight and select Mix Monitor in the 

Function List to obtain the Mix Monitor display. 

MONITOR 

The Monitor screen displays each channel and shows the movement of channels 

when sticks, levers and switches are moved. It renames channels according to 

special assignments to assist in identifying each channel. For instance, when 

Flaperon is the wing type, the Monitor displays RAIL for right Aileron and LAIL 

for left Aileron instead of displaying channels 2 and 6. The Monitor function also 

displays the current value of all digital trims. 

The Monitor function also has a servo test function you can use to drive servos in 

selected movement types. Some of these include setting all servos to the neutral 

position, SLOW to move all servos slowly in both directions, QUICK to drive 

all servos quickly in both directions, and STEP to drive one servo at a time one 

direction through all 11 channels quickly. Finally, you can then repeat one servo 

at a time in the other direction quickly. 

1 To access the Monitor function, highlight and select MONITOR in the 

Function List to obtain the Monitor display. 

2 The default display shows the graphical positions of all channels. To view 

the digital trim positions for all trims, highlight and select PAGE. View 

both displays while moving sticks, switches and trim levers to see the 

movements of various channels and trims.

FReQUeNTLy ASkeD QUeSTIONS 

ON SPEKTRUM 2.4GHz 

Your DSM2 equipped 2.4GHz system is intuitive to operate, functioning 

nearly identically to FM systems. Following are a few common questions from 

customers: 

Q: After I’ve bound the receiver to my transmitter, which do I turn 

on first when I want to fly? 

A: Either one. Every DSM 2.4GHz transmitter has a GUID (Globally Unique 

Identifier) code imbedded in its signal. When you bind a DSM receiver 

to your transmitter, this GUID code is stored in the receiver. If you turn 

the receiver on before the transmitter, you don’t have to worry about it 

responding to another transmitter. The receiver will inhibit throttle output 

and drive all controls to preset positions while it waits for a signal from the 

transmitter with the same GUID code it has stored. 

If a DSM transmitter is turned on first you can expect it to connect within 6 

seconds of powering on the receiver. 

Q: Sometimes the system takes longer to connect or doesn’t 

connect at all. Why? 

A: In order for a DSM system to connect, the receiver must receive a large 

number of uninterrupted signal packets from the transmitter. This process 

takes just a few seconds, but if the transmitter is too close to the receiver 

(within 4 feet) or near metal objects it may detect its own reflected 2.4GHz 

energy as “noise”. This can delay or prevent connection. 

If this happens make sure you are a sufficient distance from metal objects 

and the receiver itself before you power up and try again. 

Q: Is it true that DSM systems are less tolerant of low voltage? 

A: All DSM receivers require at least 3.5V to operate normally. Most servos 

cease to operate below 3.8V. Using multiple high-voltage servos, however, 

with an inadequate power supply can allow voltage to momentarily drop 

below 3.5V. This will cause the receiver to “brown out” and reconnect. 

All recently manufactured JR and Spektrum DSM receivers feature 

QuickConnect technology that will reconnect the system within a quarter of 

a second should a brownout occur. In addition, the receiver’s LED will flash, 

indicating a brownout has occurred. If after landing you notice your DSM 

receiver’s LED is flashing, make sure you have adequate power before you 

fly again. 

Q: Sometimes when I power on my DSM system I notice the 

receiver won’t connect and it needs to be rebound to the 

transmitter. Can this happen in flight? 

A: No. A DSM receiver cannot be unbound from its transmitter without specific 

action by the user. 

You can accidentally unbind a receiver by inadvertently pressing the bind 

button on your transmitter when you turn it on. This causes the transmitter 

to go into bind mode. If this happens and the transmitter doesn’t detect a 

binding signal from the receiver it can cause the receiver to be unbound. 

Some transmitter stands can cause the bind button to be depressed during 

power up, but these instances are extremely rare. 

If your system fails to connect, chances are much greater that it’s the result 

of one of the following conditions and not because the receiver is unbound. 

1. You’ve selected the wrong model memory. 

2. The transmitter is too close to conductive material to connect 

(see FAQ #2). 

Q: How important is it that I test my system using a Spektrum 

flight Log? 

A: All 2.4GHz signals, not just DSM, are affected by proximity to conductive 

materials such as carbon fiber or metal. Few RTF and ARF sport airplanes 

or helicopters use enough of these kinds of materials for it to be an issue. 

If, however, you’re flying a sophisticated model that uses a lot of conductive 

materials in its construction, a Flight Log can be helpful. The information it 

collects when you fly will help you determine the optimum location for your 

receiver(s) so you can minimize the effects of these materials on your signal 

performance. For more details on the Flight Log and how it works, visit 

SpektrumRC.com. 

GENERAL INfORMATION 

Servo Precautions 

• Do not lubricate servo gears or motors. 

• Do not overload retract servos during retracted or extended conditions. Make 

sure they are able to travel their full deflection. Overloading or stalling a 

servo can cause excessive current drain. 

• Make sure all servos move freely through their rotations and no linkages 

hang up or bind. A binding control linkage can cause a servo to draw 

excessive current. A stalled servo can drain a battery pack in a matter of 

minutes. 

• Correct any control surface “buzz” or “flutter” as soon as it is noticed in 

flight, as this condition 

can destroy the feedback potentiometer in the servo. It may be extremely 

dangerous to ignore such “buzz” or “flutter.” 

• Use the supplied rubber grommets and brass servo eyelets when mounting 

your servos. Do not over-tighten the servo mounting screws, as this negates 

the dampening effect of the rubber grommets. 

• Ensure the servo horn is securely fastened to the servo. Use only the servo 

arm screws provided; the size is different from other manufacturers. 

• Discontinue to use servo arms when they become “yellowed” or discolored. 

Such servo arms may be brittle and can snap at any time, possibly causing 

the aircraft to crash. 

• Check all related mounting screws and linkages frequently. Aircraft often 

vibrate, causing linkages and screws to loosen. 

General Notes 

Radio controlled models are a great source of 

pleasure. Unfortunately, they can also pose a 

potential hazard if not operated and maintained 

properly. 

It is imperative to install your radio control 

system correctly. Additionally, your level of 

piloting competency must be high enough to 

ensure that you are able to control your aircraft 

under all conditions. If you are a newcomer to 

radio controlled flying, please seek help from an 

experienced pilot or your local hobby store. 

Safety, Precautions, and Warnings 

As the user of this product, you are solely 

responsible for operating it in a manner that does 

not endanger yourself and others or result in 

damage to the product or the property of others. 

Carefully follow the directions and warnings for 

this and any optional support equipment (chargers, 

rechargeable battery packs, etc.) that you use. 

This model is controlled by a radio signal that 

is subject to interference from many sources 

outside your control. This interference can cause 

momentary loss of control so it is necessary to 

always keep a safe distance in all directions around 

your model, as this margin will help to avoid 

collisions or injury. 

• Always operate your model in an open area away from cars, traffic, or 

people. 

• Avoid operating your model in the street where injury or damage can occur. 

• Never operate the model out into the street or populated areas for any 

reason. 

• Never operate your model with low transmitter batteries. 

• Carefully follow the directions and warnings for this and any optional 

support equipment (chargers, rechargeable battery packs, etc.) that you use. 

• Keep all chemicals, small parts and anything electrical out of the reach of 

children. 

• Moisture causes damage to electronics. Avoid water exposure to all 

equipment not specifically designed and protected for this purpose. 

Safety Do’s and Don’ts for Pilots 

• Ensure that your batteries have been properly charged prior to your initial 

flight. 

• Keep track of the time the system is turned on so you will know how long 

you can safely operate 

your system. 

• Perform a ground range check prior to the initial flight of the day. See the 

“Daily Flight Checks Section” for information. 

• Check all control surfaces prior to each takeoff. 

• Do not fly your model near spectators, parking areas or any other area that 

could result in injury to people or damage of property. 

• Do not fly during adverse weather conditions. Poor visibility can cause 

disorientation and loss of control of your aircraft. Strong winds can cause 

similar problems. 

• Do not point the transmitter antenna directly toward the model. The radiation 

pattern from the tip of the antenna is inherently low. 

• Do not take chances. If at any time during flight you observe any erratic or 

abnormal operation, land immediately and do not resume flight until the 

cause of the problem has been ascertained and corrected. Safety can never 

be taken lightly.

Purpose 

This advisory outlines safety standards for 

operations of model aircraft. We encourage 

voluntary compliance with these standards. 

Background 

Attention has been drawn to the increase in model 

aircraft operation. There is a need for added caution 

when operating free flight and radio controlled craft 

in order to avoid creating a noise nuisance or a 

potential hazard to full-scale aircraft and persons 

and/or property on the surface. 

Operating Standards 

Modelers generally are concerned with safety and 

exercise good judgment when flying model aircraft. 

However, in the interest of safer skies, we encourage 

operators of radio controlled and free flight models 

to comply with the following standards:

a. Exercise vigilance in locating full-scale aircraft (get help if possible) so as not to 

create a collision hazard. 

b. Select an operating site at sufficient distance from populated areas so you do 

not create a noise problem or a potential hazard. 

c. Do not fly higher than 400 feet above the surface. 

d. Always operate more than three miles from the boundary of an airport unless 

you are given permission to be closer by the appropriate air traffic control 

facility in the case of an airport for which a control zone has been designated or 

by the airport manager in the case of other airports. 

e. Do not hesitate to ask for assistance in complying with these guidelines at the 

airport traffic control tower or air route traffic control center nearest the site of 

your proposed operation. 

Information Provided By 

Director, Air Traffic Service Federal Aviation Administration, Washington, D.C. 

Daily Flight Checks 

1. Check the battery voltage on both the transmitter and the receiver battery 

packs. Do not fly below 4.3V on the transmitter or below 9V on the receiver. 

To do so can crash your aircraft. 

Note: When you check these batteries, ensure that you have the polarities 

correct on your expanded scale voltmeter. 

2. Check all hardware (linkages, screws, nuts, and bolts) prior to each day’s 

flight. Be sure that binding does not occur and that all parts are properly 

secured. 

3. Ensure that all surfaces are moving in the proper manner. 

4. Perform a ground range check before each day’s flying session. 

5. Prior to starting your aircraft, turn off your transmitter, then turn it back 

on. Do this each time you start your aircraft. If any critical switches are on 

without your knowledge, the transmitter alarm will warn you at this time. 

6. Check that all trim levers are in the proper location. 

7. All servo pigtails and switch harness plugs should be secured in the 

receiver. Make sure that the switch harness moves freely in both directions.

This product contains a radio transmitter with 

wireless technology which has been tested 

and found to be compliant with the applicable 

regulations governing a radio transmitter in the 

2.400GHz to 2.4835GHz frequency range. 

ANTENNA SEPARATION DISTANCE 

When operating your Spektrum transmitter, please 

be sure to maintain a separation distance of at least 

5 cm between your body (excluding fingers, hands, 

wrists, ankles and feet) and the antenna to meet 

RF exposure safety requirements as determined by 

FCC regulations. 

The illustrations below show the approximate 5 cm 

RF exposure area and typical hand placement when 

operating your Spektrum transmitter. 

APPENDIX 

FLIGHT LOG JRPA145 - OPTIONAL 

FOR JR R921 ReCeIVeR 

The Flight Log is compatible with the JR R921 receiver and many other 

compatible receivers. The Flight Log displays overall RF link performance as well 

as the individual internal and external receiver link data. Additionally it displays 

receiver voltage. 

After a flight and before turning off the receiver or transmitter, plug the Flight Log 

into the Data port on the receiver. The screen automatically displays voltage e.g., 

6v2= 6.2 volts . 

Note: When the voltage reaches 4.8 volts or less, the screen flashes indicating 

low voltage. 

Using the flight Log 

Press the button to display the following information: 

• A - Antenna fades on internal antenna A 

• B - Antenna fades on external antenna B 

• L - Antenna fades on the left external antenna 

• R - Antenna fades on the right external antenna 

• F - Frame loss 

• H - Holds 

Antenna fades—represents the loss of a bit of information on that specific antenna. 

It’s typical to have as many as 50 to 100 antenna fades during a flight. 

If any single antenna experiences over 500 fades in a single flight, reposition the 

antenna in the aircraft to optimize the RF link. 

Frame loss—represents simultaneous antenna fades on all attached receivers. 

If the RF link is performing optimally, frame losses per flight should be less than 

20. 

Holds are indicated when 45 consecutive frame losses occur. 

This takes about one second. If a hold occurs during a flight, it’s important to 

re-evaluate the system. Move the antennas to different locations and/or check to 

be sure the transmitter and receivers are working correctly. 

Note: You can use a servo extension to plug the Flight Log in without having 

to remove the aircraft’s hatch or canopy. On some models, the Flight Log can 

be plugged in, attached and left on the model using double-sided tape. This is 

common with helicopters, mounting the Flight Log conveniently to the side frame. 

ADvANCED RANGE TESTING 

Advanced Range Testing Using a flight Log 

For sophisticated aircraft that contain significant amounts of conductive materials 

(e.g., turbine-powered jets, some types of scale aircraft, aircraft with carbon 

fuselages, etc.) the following advanced range check confirms internal and remote 

receivers are operating optimally and the receiver installation is optimized for the 

specific aircraft. Before each flying session, and especially with a new model, it’s 

important to perform a range check. The 11X incorporates a range testing system 

which, when the bind button on the transmitter is pressed and held, reduces the 

output power, allowing a range check. 

Plug a Flight Log (optional, JRPA145) into the data port in the receiver and turn 

on the system (Tx and Rx). Advance the Flight Log until F- frame losses display 

by pressing the button on the flight log. 

Have a helper hold your aircraft while observing the Flight Log data. Stand 30 

paces away from the model and helper. Face the model with the transmitter in 

your normal flying position and depress and hold the bind button on the back of 

the transmitter. This causes reduced power output from the transmitter. 

Have your helper position the model in various orientations (nose up, nose down, 

nose toward the transmitter, nose away from the transmitter, etc.) while watching 

the Flight Log. Note any correlation between the aircraft’s orientation and Frame 

Losses. Do this for 1 minute. You can use the timer on the transmitter. 

For giant-scale aircraft, tip the airplane up on its nose and rotate it 360 degrees 

for one minute then record the data. Next place the airplane on its wheels and do 

a second test rotating the aircraft in all directions for one minute. After one minute 

release the bind button. A successful range check will have less than ten recorded 

frame losses. 

Scrolling the Flight Log through the Antenna fades (A, B, L, R) allows you to 

evaluate the performance of each receiver. Antenna fades should be relatively 

uniform. If a specific antenna is experiencing a high degree of fades, then that 

antenna should be moved to a different location. 

A successful Advanced test yields the following: 

• H- 0 holds 

• F- Less than 10 frame losses 

• A, B, R, L- Frame losses will typically be less than 100. 

It’s important to compare the relative frame losses. If a particular receiver has a 

significantly higher frame loss value (2X to 3X), redo the test. If the same results 

occur, move the offending receiver to a different location. 

CONTROL STICK TENSION 

ADJUSTMENT 

Stick tension adjustments are accessible by removing the back half of the 

transmitter case. Remove the 6 screws with a medium Phillips screwdriver, then 

carefully pull the back half of the transmitter case off gently. Set the case to the 

side using care to not damage the wires. Using a small Phillips screwdriver, 

adjust each gimbals’ tension screw for the desired tension (counterclockwise to 

loosen stick tension; clockwise to tighten stick tension).

Control Stick Length 

Use a 2mm Allen wrench to unlock the setscrew to adjust the stick length. Turn 

the wrench counterclockwise to loosen the screw. Then, turn the stick clockwise 

to shorten or counterclockwise to lengthen the overall stick length. After the 

control stick length has been adjusted to suit your flying style, tighten the 2mm 

setscrew. If you desire longer sticks, JR offers a stick (JRPA047) approximately 

one inch longer than standard, and has various length anodized aluminum stick 

ends available (JRPA040-JRPA045). These stick ends are crafted from bar stock 

aluminum, and are available at your local JR dealer. 

Neck Strap Attachment 

The face of the 11X transmitter has an eyelet for connecting a Neck Strap.
